Please answer this question it is very impoertant it's for my assignment
 
Rainfall is very important because the presence of water in an environment (in all its forms: liquid, gas and solid) is a major factor in the distribution and exchange of energy. The presence of water brought by rainfall, proximity to water bodies, etc., makes temperatures more stable.

Because water has high *specific heat* (see more about this in the link below), water masses can absorb and keep large amounts of the caloric energy (heat) that reaches our planet from the sun, and also of the heat that the planet itself radiates back out to space, with relatively small changes of temperature. Water can then release this "trapped" heat when it's cold, so that temperature variations are smaller than in arid places where the land and air is "dry".
 
Well i mean it depends on what kind of time scale your talking about, and how much, and when, etc... For example if you taken 1000 years of average 30 inches of rainfall every 6 months, it can effect the climate a lot. Your going to have more water, means more plants, that mean more oxygen in the air, and .... everything is connected. Also rainfall can erode rocks, make lakes, thus decreasing temperatures around that area. Like when you go near coastal areas it's usually cooler, and more moist. So water can cool things down, clean the air, make the air more moist, and drop over all temperatures. But know that climate is something that is on a big scale. It takes long periods of time to change climates.
