What is the relationship between air pressure and temperature, wind speed and cloud cover?

Generally speaking, where the temperature near the ground is high, the air pressure is low, and the air pressure at high altitude is opposite to that near the ground.

The greater the temperature difference per unit distance, the greater the pressure difference, the denser the isobar and the greater the wind speed.

When the temperature is high, the airflow rises (low pressure near the ground), the water vapor cools and condenses, and a large number of clouds are easy to form rainy weather.
