The Caspian Sea Regions

There are three Caspian regions. They are very different from each other. The northern region is called the Caspian shelf. This region is quite shallow. The Middle Caspian region is deeper than the previous one. The Southern region is the deepest. The northern part freezes first, during winter, since it is the shallowest area. Temperature of water in the Southern Region is in average some thirteen degrees C, but when winter comes, the temperature goes down to some six degrees. During the summer season, it gets considerably higher – up to twenty five degrees. The Middle Caspian Region is more dynamic when it comes to temperature oscillations. The average water temperature during winter is six degrees, and in the summer, it is some twenty degrees higher. In the northern region, temperature oscillations are drastic; however, this area is very shallow, so the water here is not stratified by temperature.

This lake is very stormy, however, with the choppiness force of 6. Both horizontal and vertical movements are strong.

There are more than 132 rivers that flow into the Caspian Sea. The biggest one of them is Volga. Amu Darya and Sir Darya are also in this group of rivers.
