Sudestada

As Sudestada a local refers to wind from the southeast ( Spanish sudeste ) and the associated weather in southern South America , particularly in Argentina and Uruguay .

The Sudestada brings humid, cold Atlantic air far into the subtropics and, especially in the Pampa region, ensures long-lasting, heavy rains, which often lead to flooding. In the area of ​​the Río de la Plata in Buenos Aires, for example, it causes flooding in the lower lying areas near the river, as the southeast wind pushes the water upstream. The further it penetrates to the northwest, the precipitation decreases significantly. From a meteorological point of view, the Sudestada is the back of low pressure areas .

Sudestadas are most common in winter and spring and are often harbingers of warmer periods. A strong Sudestada occurs as a weather rule in many years in September; she was given the name Santa Rosa .
