This image shows the reflectivity area from the attention wall of Hurricane Andrew. The symmetry proven in this image indicates that Andrew was a really nicely developed hurricane. The ring of orange are the excessive reflectivities associated with the convection discovered in the eye wall.

Snow and light-weight drizzle each produce radar reflectivity with about the identical worth. Melting snow and moderate rain even have comparable values. Very excessive reflectivity’s (the greys on the dimensions on the picture above) are at all times associated with hail.

The forefront of an advancing warmer air mass, the passage of which generally brings cloud and precipitation followed by increasing temperature and/or humidity. The vanguard of an advancing colder air mass. Its passage is normally marked by cloud and precipitation, adopted by a drop in temperature and/or humidity. This picture reveals the different scales on which snow can happen. The massive snow band extending throughout the figure is associated with a big storm system moving throughout the nation.

Tornadoes are often positioned at the center of a hook-shaped echo on the southwest facet of thunderstorms. The hook is best observed in the reflectivity …
