The main factor affecting the difference in summer temperatures in my country is _______

1. The first factor is the daytime. When the direct point is in the northern hemisphere, the days are longer and the nights are shorter in all parts of the northern hemisphere, and the further north (the higher the latitude), the longer the day. Therefore, North China and Northwest China The daylight hours in summer are longer than in the south, which means longer hours of sunshine.

2. Weather factors. The influence of weather on temperature is mainly achieved through cloudiness and sunshine. Although summer is the rainy season in the monsoon area in eastern my country, there are still differences between the north and the south. In other words, the rainy season in northern my country is shorter than that in southern China, with less precipitation and more sunny days. It weakens solar radiation less than in the south, which is conducive to rising temperatures.
