Sea of ​​Azov water temperature in early June. Water temperature in the Sea of ​​Azov in June. Water temperature in June in the Sea of ​​Azov - in detail

Temperature of surface layers sea ​​water in the Black and Azov Seas, completely depends on the time of year and time of day, in the open sea it fluctuates on average from 6 to 25 °C, reaching 30 °C in shallow water.

The Sea of ​​Azov is the northeastern lateral basin of the Black Sea, with which it is connected by the Kerch Strait, in ancient times the Cimmerian Bosphorus. The width of the strait at its narrowest point is 4.2 km. This is the shallowest sea in the world, its depth does not exceed 15 meters.

Black Sea - inland sea of ​​the basin Atlantic Ocean. The Bosphorus connects with the Sea of ​​Marmara, then, through the Dardanelles, with the Aegean and mediterranean seas. The Kerch Strait connects with the Sea of ​​Azov. From the north, the Crimean peninsula cuts deep into the sea. The water boundary between Europe and Asia Minor runs along the surface of the Black Sea. The area is 422,000 km2. The outlines of the Black Sea resemble an oval with the largest axis about 1150 km. The greatest length of the sea from north to south is 580 km. The greatest depth is 2210 m, the average is 1240 m.

The water temperature field is built on the basis of data from operational satellite and ground-based observations.

The map was built at the Hydrometeorological Center of Russia according to NCDC/NOAA data.

For Sea of ​​Azov characterized by significant temporal and spatial variability of thermal conditions. This feature is explained geographic location on the southern periphery temperate latitudes(on the border of freezing and non-freezing seas), the shallowness of the Sea of ​​Azov, the indentation of its coasts, relatively low salinity, etc. The interaction of all these factors determines the characteristics of the thermal conditions of the Sea of ​​Azov.

The main source of heat entering the surface of the Sea of ​​Azov is solar radiation. The amount of total solar radiation absorbed by the Sea of ​​Azov per year, on average over a long period, is about 4000 MJ/m2. Of this amount of heat, 2200 MJ/m2 is spent annually for evaporation, about 1500 MJ/m2 for effective radiation, and 300 MJ/m2 for contact heat exchange with the atmosphere. The heat balance of the surface of the Sea of ​​Azov is covered in detail on the page dedicated to climate.

Water exchange with the Black Sea, as well as the runoff of the Don and Kuban, have an insignificant effect on the thermal regime of the Sea of ​​Azov. On average, for a year, the waters of the Don cool the sea, while the Black Sea and Kuban waters warm it. A quantitative assessment of the thermal effect of the above factors, related to the entire sea area, showed that the cooling effect of the Don is about 0.8 MJ/m2 per year, and the warming effect of the Kuban and Black Sea waters is 2.1 and 7.5 MJ/m2, respectively.

The predominant role of radiation factors in the formation thermal regime The Sea of ​​Azov is clearly seen in the zonal distribution of the average annual long-term values ​​of water temperature according to data from coastal stations. They gradually increase from 11.2°C in the northern part of the Sea of ​​Azov to 12.2-12.4°C in the south, i.e. by about 0.5°C per 1° latitude. There are no distinct trends in the long-term course of temperature. Visually, one can distinguish a slightly lower background of the temperature of the Sea of ​​Azov in the second half of the 20s - in the early 30s and an increased one - in the second half of the 60s - early 70s.

The calculation of long-term linear trends from the second half of the 1940s to 1986 showed practically no trend in Berdyansk and a slight positive trend (0.03 °C) in Mysovoy. The latter circumstance may be due to some increase in the warming effect of the Black Sea waters in the cold part of the year (October-February) in connection with the construction of the Tsimlyansk hydroelectric complex and an increase in river runoff withdrawals. This is to some extent confirmed by calculations of long-term trends. average monthly temperature waters of the Sea of ​​Azov. It also follows from these data that the trends of monthly values ​​are much larger than those of the annual ones, but in general, over the year, with long-term averaging, they practically balance out.

Seasonal changes in the water temperature of the Sea of ​​Azov, as well as other shallow water areas of temperate latitudes, are very pronounced. The average monthly long-term values ​​of water temperature at the coastal hydrometeorological stations of the Sea of ​​Azov indicate the following. The range of the annual course in different areas of the Sea of ​​Azov is 23.2-24.7 ° C, and it decreases somewhat in the direction from north to south, mainly due to the difference between the lowest temperatures in the northern and southern regions of the Sea of ​​Azov.

The most low temperature observed in January-February, and the highest - in July. During the period of greatest warming, the water temperature practically levels off throughout the Sea of ​​Azov. From the beginning of cooling (August), the water temperature in the southern part of the Sea of ​​Azov becomes higher than the temperature in the northern and central regions. From April to July the picture is reversed. This is probably due not only to the zonal location of observation points and morphological features regions, but also with the warming effect of the Black Sea waters on the southern regions of the Azov Sea during the cooling period, and with their cooling effect during the period of intense warming of the shallow Azov Sea. In open deeper areas of the Sea of ​​Azov, the maximum water temperature is observed in August.

The most intense warming of the waters in spring can be traced from April to May. According to coastal stations, at different points it is rounded at 7-9 °С (average 7.9 °С), in open areas of the Sea of ​​Azov - 6.5-9.5 °С (average 8.4 °С). The most rapid cooling of waters near the coast occurs from September to October by 6-7 °С (average 6.5 °С), and in the open areas of the Sea of ​​Azov from October to November - by 5.5-7.7 °С (average 6.5 °С). .7 °C).

The seasonal course of water temperature at coastal stations differs little from that in the shallow areas of the Sea of ​​Azov and differs significantly from the seasonal course in deep water areas. The maxima of the curves are shifted by about half a month; during the period of heat accumulation, the water temperature in shallow water areas is higher than in deep water areas, and vice versa during the cooling period.

Monthly values ​​of water temperature have much greater variability than average annual ones. Thus, according to the data of the Mysovoe and Berdyansk hydrometeorological stations, the standard deviations vary from 0.7 to 2.2 °C in different months. Their greatest values ​​are in April and October, i.e., at the time of the most intense seasonal temperature changes. The least - for the summer and early autumn, when the rate of seasonal changes in the water temperature of the Sea of ​​Azov is underestimated, as well as for January-February in Berdyansk, where the ice cover helps to stabilize the temperature. Data on open areas of the Sea of ​​Azov are not enough to obtain quantitative characteristics standard deviations monthly values ​​of water temperature, but their qualitative analysis as a whole confirms the results obtained from the data of coastal stations. Some difference is that in the open sea in May the deviations are somewhat greater than in April. Most high values water temperatures, according to urgent observations at coastal stations, are observed in July and in different areas of the Sea of ​​Azov are 29.3-32.8 ° С. The lowest (from -2.4 °С in Genichesk to -0.5 °С in Taganrog) can be observed in any of the winter months.

The spatial distribution of water temperature in the waters of the Sea of ​​Azov due to its small sizes and shallow depths is characterized by poor contrast. According to coastal stations, during the period of greatest cooling (February), the average water temperature in the surface layer of the sea varies from 0-0.2 °С in the northern part of the sea to 1.0-1.2 °С in the southern part. There are very few data for open areas of the Sea of ​​Azov in winter. However, since the heat reserve of waters here is greater than in coastal areas, it should be expected that the water temperature should also be somewhat higher than the indicated limits.

The temperature field during the period of the greatest warming of waters (July-August) also differs in low contrast. The average values ​​of water temperature in the surface layer of the Sea of ​​Azov, both in coastal areas and in the open sea, vary within 24-25 °C. During periods of warming up and cooling down, temperature contrasts increase. So, in April, water off the coast warms up to 8-11 °C, and in open areas of the sea it is below 7 °C (in the central part of the Sea of ​​Azov it does not exceed 5.5 °C). In October, the water temperature in almost the entire open water area is above 14 °C, and in coastal areas, with the exception of the southernmost ones, it is below 14 °C.

Spatial distribution of water temperature in the bottom layer of the Sea of ​​Azov in in general terms similar to the distribution in the surface layer. During the cooling period, the temperature background in the bottom layers, especially in the deep areas, is somewhat higher than near the surface, and during the warming period, on the contrary, it is lower. From the analysis of the available database, it follows that, starting from October, the average water temperature in the bottom layers in most areas becomes higher than in the surface, with the exception of the deepest areas, where, due to the greater heat capacity of the water masses, their cooling near the surface, and at the bottom it is slower than in the shallow waters of the Sea of ​​Azov.

In November, apparently, a weak unstable vertical temperature stratification is established everywhere, which is easily destroyed by wind-wave mixing and, after reaching the vertical winter convection to the bottom, is replaced by homothermy. From March-April, the restructuring of the vertical thermal structure of the water of the Sea of ​​\u200b\u200bAzov begins. Weak stable stratification is formed in most areas of the sea, with the exception of the deepest areas of the central part of the sea and the southwestern squares, where the temperature of the surface layer of the Sea of ​​Azov is lower than the temperature of the bottom layers due to the accumulation here in spring under the influence of the prevailing winds of drifting ice. Stable thermal stratification persists on average from May to September. The vertical temperature stratification of the waters of the Sea of ​​Azov is usually insignificant.

The calculation of the repeatability of temperature differences in the surface and near-bottom layers, made according to observations at offshore stations, showed that in the majority of cases the difference does not exceed 1 °C, but in some cases, with weak winds and significant salinity gradients, it can reach 5-7 °C.

Analysis of data on selected shallow water squares of the Sea of ​​Azov with largest number observations (depths of 4-6 m) and deeper areas (depths of 10-12 m) made it possible to reveal some features of the vertical thermal structure in different areas of the Sea of ​​Azov. First, they confirm the weak temperature stratification of the sea waters. The average vertical gradients both in shallow and inland areas do not exceed 0.12–0.13 °C/m. Secondly, there is a noticeable difference in the formation of the vertical thermal structure in areas with different depths during the navigation period. In shallow water areas, where the water heating in the upper and bottom layers occurs with a slight time shift, the gradients gradually increase and reach highest values in July, when the surface layer of water is maximally warmed up. With the beginning of its cooling, the gradients decrease, and in October the stratification becomes unstable.

In the deep areas of the Sea of ​​Azov, where the bottom layers warm up more slowly with a significant lag behind the surface layer warming, the largest gradients are established already in May-June, and then begin to decrease. In April and October, homothermy or weak instability is practically established.

An essential addition to the characterization temperature regime Sea of ​​Azov is the analysis of internal and external heat transfer. The calculation of heat transfer, in essence, is a continuation of the calculation of the heat balance. The external heat exchange is considered to be half the sum absolute values the incoming and outgoing parts of the heat balance of the surface of the Sea of ​​Azov, and the internal heat exchange - the difference between the maximum and minimum heat content of the water mass.

On the shallow Sea of ​​Azov, which occupies a small area, there are no pronounced climatic regions, however, two different zones of external heat circulation can be distinguished here. One of them is located in the central part of the Sea of ​​Azov, the other - in the coastal shallow area, including the Taganrog Bay. The difference between the external heat exchange of these zones per year is 800 MJ/m2. As the maps of the external heat transfer show, its maximum values ​​are located in the central, deep-water part of the Sea of ​​Azov, and the minimum values ​​are in the shallow water, and the contours of the external heat transfer in general terms repeat the isobaths. The dependence of the external heat exchange on the depth of the Sea of ​​Azov is closely related to the annual amplitudes of the heat balance. In those areas where the amplitude of the heat balance is higher, the external heat transfer is greater, the minimum values ​​of the heat transfer are located in areas with a lower amplitude of the heat balance. The close relationship between the heat balance of the Sea of ​​Azov and depth is explained by the fact that the active layer is the entire water column and with increasing depth due to a decrease in the expenditure part of the heat balance (lower water temperature in the deep part and the associated lower heat loss for evaporation) the final value of the balance increases. The maximum and minimum values ​​of the external heat exchange per year are about 1200 and 400 MJ/m2, respectively.

The distribution of internal heat circulation in general terms repeats the distribution of external heat, and the depth of the Sea of ​​Azov is of decisive importance here too. This is explained by the fact that the extreme values ​​of heat content in the small and shallow Sea of ​​Azov occur during periods when the entire mass of water has almost the same temperature, and the heat reserve is determined only by depth, on which the spatial distribution of internal heat exchange depends.

The internal heat exchange is slightly less than the external one. For the entire sea, the difference between the total values ​​of external and internal heat exchange for the year is 113 MJ/m2. Following the arguments of V.S. Samoylenko on the effect of ice cover on the discrepancies in the values ​​of the external and internal heat exchanges of the Sea of ​​Azov, this difference can be attributed to heat losses during ice formation. Approximate calculations of the possible thickness of ice (average over the sea), which should form by the end of winter according to the formula he proposed, and a comparison of the obtained value with actual data, allow us to consider this assumption legitimate.

The processes of ice formation and ice melting are reflected not only in the internal, but also in the external heat circulation of the Sea of ​​Azov. During the period of ice melting and the removal of ice to the southern regions of the Sea of ​​Azov, there is a slight decrease in water temperature and, as a result, a decrease in the expenditure part of the heat balance, thereby affecting the external heat transfer.

Records for water temperature in the Sea of ​​Azov in June

It has been monitoring the sea water temperature in the Sea of ​​Azov since 2010. And, I must say, water temperature records happen quite often. Almost every day at a particular resort, the water is either the coldest or the warmest. Below are the minimum and maximum temperatures water in the sea in the Sea of ​​Azov in June.

What is the water temperature in the Sea of ​​Azov? And in Black? Where do you go anyway? Perhaps now all these questions are as relevant as possible. It's time for summer holidays and everyone wants to go to the sea for at least a week, take a break from the bustle of the city, din and constant haste.

Water temperature in the Sea of ​​Azov. general description object

If you delve into history, you can quickly find out that in ancient times no Sea of ​​​​Azov existed, but simply flowed into the Black Sea at the site of the modern Kerch Strait.

In ancient times, the Greeks called it the Meotian Lake, a little later the Romans renamed it the swamp of the same name.

Throughout history, the sea has been renamed several times: Balyk-Dengiz, Mayutis, Saks Sea, Salakar, Samakush, Chabak-Dengiz. And only in the second half of the 18th century, the name Sea of ​​\u200b\u200bAzov was assigned to the reservoir, which probably occurred on behalf of the Polovtsian prince Azum (Azuf) killed on its shores.

The Sea of ​​Azov can be classified as an inland sea located in the eastern part of Europe. According to experts, only by understanding its nature and characteristics, it is possible to draw the correct conclusion about the temperature differences of this reservoir.

First of all, it should be noted that the Sea of ​​\u200b\u200bAzov is considered the shallowest in the world, its depth does not exceed fourteen meters, while the average, fluctuating within marks of 6.8-8 m, is 7.4 m.

Water temperature in the Sea of ​​Azov. What is it due to?

From the point of view of scientists, this object is characterized by both high temporal and spatial variability of the main thermal conditions. This feature can be explained by the presence of several factors at once:

• geographical location, because the sea is located just on the border of two types of seas: freezing and non-freezing;
• significant shallowness;
• sufficient indentation of the coast;
• low salinity.

The main source of heat, which abundantly enters the sea surface, is If calculated as a whole, then Azov is capable of absorbing 4000 MJ / m2 of the energy of the celestial body per year. Of this amount, 2200 MJ/m2 is needed for evaporation, 1500 MJ/m2 is used for effective radiation, and only 300 MJ/m2 is used for contact heat exchange with the environment.

A significant role is also played by water exchange with the neighboring Black Sea, as well as the flow of two full-flowing rivers - the Kuban and the Don. Although their influence is different. For example, the Kuban and the Black Sea make the waters of Azov warmer, but the Don, on the contrary, significantly cools.

Not so long ago, scientists conducted a selective analysis of data in different squares of the reservoir. As a result, it turned out that the water temperature in the Sea of ​​Azov can also be characterized in terms of vertical thermal structure. The most stable indicators were observed from May to July, when the water, starting from shallow water, gradually warmed up, reaching its maximum value. Further, a process of stable cooling is observed, and, finally, in October, stratification becomes completely unstable.

Water temperature in the Sea of ​​Azov in warm and cold seasons

Monthly water temperature values ​​are very variable, in contrast to the average annual ones, which, according to experts, are quite stable. The water temperature of the Sea of ​​Azov is controlled by two hydrometeorological stations located in Berdyansk and Mysovoy. Installed modern instruments show that standard monthly deviations range from 0.7 to 2.2 °C.

Their highest coefficients fall on April and October, i.e., precisely at the time when the most intense seasonal temperature changes are observed.

The smallest can be noted in summer and at the very beginning of autumn. At this time, the rate of seasonal changes in water temperature is underestimated. The same situation is observed in January-February, but only in Berdyansk, because. here the ice cover stabilizes the temperature considerably.

Note that the highest temperature values ​​of water are in the range of 29.3-32.8 °C. The lowest ones are from approximately -2.4 °С in the city of Genichesk to about -0.5 °С in the city of Taganrog.
