Why does the wind get colder when the cold front crosses the border, and it rains even when the warm front crosses the border?

When the cold front crosses the border, cold air is stronger than warm air, and warm air is forced to rise. It rained behind the front, and the area originally covered by warm air was replaced by cold air. The cold air is dry and cold, and there will be strong winds to cool down. On the contrary, when the warm front crosses the border, the momentum of warm air is stronger than that of cold air. When warm air rises, it rains in front of the front, and the area covered by cold air is replaced by warm air. Warm air is warm and humid, and it is easy to form rain when the height becomes higher. However, due to the slow action of warm air, there will be continuous rainy weather.
