Explanation:
Detailed explanation-1: -In today’s weather explainer we learn about a phenomenon called virga. Answering why you may see green on the radar but no rain is falling.
Detailed explanation-2: -Weather radars can provide complete spatial and temporal coverage of an area from one single measurement site and as such they are ideally suited for quantitative, fine resolution rainfall measurement over a wide range of spatial and temporal scales.
