What are the climatic causes of disastrous weather such as rain and snow in southern my country and drought in northern China?

Rain and snow in the south: Basically in winter, the temperature is lower than in previous years, and is more affected by the southwest warm current from the Indian Ocean than in previous years. The climate is wetter than in previous years, combined with low temperatures, so there is more rain and snow. It may also be affected by El Ni?o.

Drought in the north: In summer, northern my country mainly has a monsoon climate. If the summer monsoon is weaker than in previous years, the rain belt will move slowly, causing flooding in the south and drought in the north. The subtropical high pressure moves further north than in previous years, resulting in high temperatures and less rain in the north, resulting in drought.

Winter drought is affected by the temperate continental climate in some parts of the north, which is cold and dry. In addition, it is adjacent to the Mongolian-Siberian high pressure. Affected by this, the climate is low and dry, so there is less precipitation.
