HELP PLEASE! TY A. How are radio waves used to create radar maps?

B. How does reflectivity help meteorologists figure out the weather shown on

radar maps?

These signals have been calibrated against actual visual and location readings for the amount of rain falling and cloud water content. Thus the computer generates a visual image according to the reflectivity of the amount of water in colors on a map.

Reflectivity of an object helps indicate the amount of water that a cloud may carry. The stronger the reflected signal from the radar signal sent out, the easier the meteorologist will be able to tell what to expect. This in turn is interpreted by the meteorologist from past experience as what to expect in the future.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
