The cause of the remarkable monsoon climate.
Due to the seasonal variation of the thermal difference between land and sea, the mainland is cold and the ocean is warm in winter, and the wind blows from the mainland to the ocean. In summer, the mainland is hot and the ocean is cold, and the wind blows from the ocean to the mainland. Air blows from the ocean to the mainland, forming an airflow opposite to the high altitude, which constitutes the summer monsoon circulation.
Explain in detail:
Seasonal changes in continents and oceans. The monsoon climate is influenced by the seasonal changes of the mainland and the ocean, and the thermal difference caused by this change causes the change of atmospheric movement, thus producing the characteristics of monsoon climate.
Response to the earth's rotation. Because the rotation of the earth affects the daily radiation balance, the parameters such as temperature and rainfall in monsoon climate change with time.
Mid-high latitude weather system. In areas close to the Asian continent in winter, cold polar cyclones bring cold air, while in summer, warm and humid air flows from the mainland to the ocean.
In addition, monsoon climate is also related to the difference between topography and ocean elevation. For example, there are often obvious differences in temperature and precipitation between mountains and plains, which is related to the influence of mountain rainfall and cold air blockage. The climate around the coastline is often wetter than inland, because the sea breeze will blow from the sea surface, bringing higher humidity.
Monsoon climate is a typical tropical and subtropical climate, which is famous for its obvious seasonal changes. In winter, the monsoon climate is usually dry and cold; Summer is often humid, with much precipitation and high temperature. This climate is widely distributed, mainly in Asia, Africa and Australia.
In a word, monsoon climate is the result of many factors. It is not only an important phenomenon in nature, but also has an important impact on human production and life. In Indian subcontinent, China, Southeast Asia and Australia, monsoon climate often affects local agriculture, transportation and energy. Therefore, the study and understanding of monsoon climate is helpful to formulate corresponding coping strategies and reduce its adverse effects on human society.
