On Thursday, a Brazilian navy ship arrived in Sao Sebastiao to help rescue the victims. The ship will serve as an emergency field hospital and is equipped with helicopters and landing craft, as well as hospital beds.

What is the scientific reason behind the rains in Brazil and what awaits the country in the coming days?

Brazil is located in the southern hemisphere and is characterized by its tropical climate, and as is well known, the areas that are under the control of the tropical climate are characterized by being hot and rainy in summer, and this is exactly what happens in Brazil, where the country witnesses the summer in which temperatures rise to very high levels It exceeds the limits of 32 degrees Celsius in some areas.

The high temperatures lead to a decrease in the surface atmospheric pressure values as a result of air expansion by heating, and thus centers of surface depressions are formed that attract wet winds from the waters of the South Atlantic Ocean, which coincide with a process of raising warm air towards the upper layers of the atmosphere, forming cumulus thunderclouds that lead to heavy thunderstorms On an almost daily basis, which caused water saturation of the land and the occurrence of floods as a result of the inability of the soil to absorb more amounts of rain, and this resulted in a surface runoff of water.

According to the weather maps in the Arab Regional Weather Center, it is expected that large areas of Brazil will be exposed during the coming days to more weather turbulence, which will result in the formation of thick cumulus clouds that lead to heavy and sometimes very heavy thunderstorms, which requires attention from the risks of more torrents and floods in the coming days. .
