Appreciation of warm weather

When the spring rain comes, the direct point of the sun moves from the equator to the Tropic of Cancer, the temperature in the northern hemisphere rises slowly, the force of warm and humid airflow becomes stronger, the force of cold air weakens, the warm and humid airflow slowly enters the inland, and the cold air gradually exits, so a spring rain warms up; When autumn rain comes, the direct point of the sun moves from the equator to the tropic of Capricorn, the temperature in the northern hemisphere drops slowly, the cold air force becomes stronger, the warm and humid air force weakens, the cold air enters the inland, and the warm and humid air force gradually withdraws, so one autumn rain is followed by another cold.

So the answer is: a spring rain and a warm: under the guidance of warm and humid airflow, the temperature will get higher and higher, so a spring rain is warm. An autumn rain is cold: with the leading of cold air, the temperature will be lower and lower, so an autumn rain is cold.
