Step-by-step explanation:
When rain changes to ice pellets, the temperature at the surface usually drops. This is because the process of rain changing to ice pellets, also known as sleet or graupel, involves the raindrops passing through a layer of freezing air near the surface. As the raindrops fall through this layer of cold air, they freeze into ice pellets.
This process releases latent heat, which is the energy absorbed or released by a substance during a change in state. In this case, as the water droplets freeze into ice pellets, they release latent heat, which slightly warms the surrounding air. However, this warming effect is generally offset by the cooling effect of the freezing air near the surface, resulting in a net drop in temperature.
It's worth noting that the specific temperature change will depend on various factors, such as the temperature and humidity of the air mass, the intensity of the precipitation, and the duration of the sleet or graupel event. In some cases, the temperature drop may be relatively small, while in other cases, it may be more significant.
