How to deal with El Nino and La Nina

1. All state departments should strengthen monitoring, early warning and forecasting, especially medium and long-term forecasting, especially meteorological and marine departments.

2, formulate plans to deal with possible major disasters, * * * cooperate with the defense of various forms of disasters that may occur. Large-scale group disasters may occur, so it is necessary to strengthen the coordination and multi-sectoral cooperation between agriculture, forestry, water and energy departments.

3, the establishment must have long-term preventive measures, especially for the possible disasters caused by drought. The climate anomaly caused by El Nino event is a continuous process of nearly 1 ~ 2 years.

4. Pay attention to various extreme weather and climate events caused by El Ni? o, such as persistent rainstorm, flood, low temperature chilling injury, persistent high temperature heat wave weather, typhoon disaster, etc.

Extended data:

Precursors for the formation of El Ni? o include: the pressure rise in the Indian Ocean, Indonesia and Australia; The sea surface pressure in Tahiti and the central and eastern Pacific Ocean decreased; The trade winds in the South Pacific weaken or blow eastward; The warm air rising near Peru makes the local desert rain; Warm air diffuses from the west coast of the Pacific Ocean to the Indian Ocean and the eastern Pacific Ocean.

When the El Ni? o phenomenon occurs, the seawater temperature in the tropical ocean in the eastern and central Pacific Ocean is abnormal and keeps warming, which changes the global climate pattern, resulting in drought in some areas and excessive rainfall in others.

When La Nina occurs, the water temperature in the eastern Pacific near the equator drops abnormally, which is characterized by obvious cooling in the eastern Pacific and global climate chaos. La Nina usually appears after El Nino.
