Day June 1 and night 2 of June on the territory of the Samara region and the whole Middle Volga weather was determined by the passage of a cold front from the West. There is a high density of thunderstorms. Heavy rains, sometimes heavy. In Chelno-vershiny day dropped 18 inches of rain in the s/a vanguard night — 25 mm. In the Big Sochi, there was a very heavy rain — 47 mm in 12 hours. Gusts of wind reached 15 m/s. Airport Chromic recorded 22 m/s. In Samara on the evening of hail with a diameter of 8 mm.
Due to the current atmosphere of the situation, local residents were able to see the amazing clouds with the rotary knobs on the base that looks like the udder. In the international classification they are called cumulonimbus videobrasil (Cumulonimbus Mammatus).
Mammatus associated with the parent thunderstorm cell and often occur immediately after a strong storm. The physics of their formation based on acecourse system of descending and ascending movements of the air against the background of a General downward flow in the rear part of the disintegrating storm clouds. The combination of a bi-directional vertical movement and leads to the formation of the characteristic shape at the base of the clouds. The common life span of these clouds varies from several minutes to several hours.
As a rule, mammatus arise in the system of intense lightning storms, typical for countries with a warm climate. However, a large thermodynamic instability of the atmosphere sometimes they can be observed in middle latitudes. The biggest occurrence videobritney clouds are to the United States. In virtue of the physico-geographical characteristics of the North American continent quite often they occur with other members of the extremely powerful convection ― supercells and tornadoes.
