Why is it not cold when it rains, but it feels cold when it evaporates after the rain?

It's simple. First of all, the initial state of the cloud is water vapor, which condenses into water droplets, and then gathers to a certain extent, and it will fall when it is carried, that is, rain. The condensation of water vapor into water droplets is exothermic. After rain, water will absorb heat when it evaporates on the ground. If it rains heavily, the water that cannot evaporate will also take away the energy on the ground. Simply put, it will take away the heat from the ground, so it will feel cold after the rain.
