Relationship between Isobar and Temperature Distribution'
Summer in the northern hemisphere is winter in the southern hemisphere: the temperature is low, the air expands with heat and contracts with cold, and the air pressure is of course high. In summer in the northern hemisphere, the temperature in Eurasia is higher than that in the Pacific Ocean and the Indian Ocean (the relationship of specific heat capacity: the specific heat capacity of water is higher than that of sand), and the air pressure is low (air flows from places with low air pressure to places with high air pressure).
Look at the isobar, which is low in the middle and high around, so it is the center of low pressure. There is rain in the center of low pressure.
On the contrary, it is sunny in the center of high pressure.
In fact, the isobar has a great relationship with the wind direction.
