Ask a few questions about high school geography (about climate)

Low pressure is cold on the left and warm on the right, which means that there are two low pressure troughs around the low pressure, forming a front, with a cold front on the left and a warm front on the right.

Low pressure trough, prevailing updraft and rainy weather;

In the summer of the northern hemisphere, due to the influence of geostrophic bias, the high pressure center of the Pacific Ocean will move to the northwest. The geostrophic deviation gradually decreases from the equator to the poles, so the geostrophic deviation on the south side of the Pacific high center is greater than that on the north side, and the Pacific high center will move northward. In addition, at this time, the land is low pressure, and the gradient force points from the ocean to the land, that is, the high pressure center of the Pacific Ocean will move westward. So the center of high pressure in the Pacific will move northwest.

I hope it helps you.
