Does typhoon belong to weather system or climate system?

Climate is a perennial condition of a place, while weather is a short-term condition of a place. Typhoon is weather, not climate. Climate is a long-term average state of atmospheric physical characteristics, which is different from weather and has stability. Time scales are months, seasons, years, years to hundreds of years. It is usually characterized by the average value and deviation value of a certain period.

Due to the high temperature expansion, the density and weight of this air decrease, and the wind near the equator is weak, so it is easy to rise and convection occurs. At the same time, the surrounding cold air flows in to replenish and then rises again. This kind of circulation will eventually make the whole column of air have higher temperature, lighter weight and lower density, forming the so-called "tropical depression". The convergence caused by the southwest monsoon and the northeast trade wind and the continuation of the original convection make the vortex with low pressure continue to deepen, that is, the air around it accelerates to flow to the center of the vortex, and the faster the flow, the greater the wind speed; When the maximum wind speed near the ground reaches or exceeds17.2m per second, we call it a typhoon.

Climate is the general state of the atmosphere in a certain region of the earth for many years, and it is the comprehensive expression of various weather processes in this period. Various statistics (mean, extreme, probability, etc. Meteorological elements (temperature, precipitation, wind, etc.). ) is the basic basis for expressing climate. The World Meteorological Organization (WMO) stipulates that the calculation time of general climate is 30 years. Climate is closely related to human society, and many countries have recorded climate phenomena for a long time.
