Meteorology is about wind speed and weather in various places ~ about weather forecast

What you said is quite special. The general rule is that it is windy during the day and windy at night.

Xuzhou is north, and the temperature rises during the day. In the afternoon or evening, due to the increase of the temperature difference between land and sea, there will be easterly backflow, so that the weak wind in the daytime will be replaced by easterly wind, and the wind speed will be relatively high, but generally it will decrease after 22 o'clock.

There should be such a situation in Suzhou, but because it is farther south, there are fewer times when the temperature difference between land and sea is large, and the pressure field in the south is generally weaker than that in the north, so it is more in line with the general law of "windy during the day and windy at night". But sometimes the same situation as Xuzhou will happen.

What you said is basically right. You can think for yourself. It's windy in winter and windy in summer? Yes! This is a universal law. Due to the small temperature difference between land and sea in summer, the pressure field is also weak. For example, the intensity of Mongolia high pressure formed in winter can reach more than 1.040 hectopascals, while the air pressure in southern China may only be 1.000 hectopascals, or even less than 1.000 hectopascals. In summer, even the subtropical high is the strongest, that is, 65,438+0,025 hectopascals.
