Tornadoes are sometimes located at the heart of a hook-formed echo on the southwest aspect of thunderstorms. The hook is finest noticed within the reflectivity area. This image shows a reflectivity field containing several hook echoes related to thunderstorms that occurred in Tennessee and Kentucky on May 18https://www.sowersoftheword.com 1995. Normallyhttps://www.sowersoftheword.com it is troublesome to differentiate precipitation type on the basis of the radar reflectivity alone.

The tighter the packinghttps://www.sowersoftheword.com the stronger the winds are. The 500 mb heights are often referred to as the sterring winds of the atmosphere. Following a selected shade will show where the winds and thus pressure methods (cyclones and anticyclones) will transfer.
The forefront of an advancing warmer air masshttps://www.sowersoftheword.com the passage of which generally brings cloud and precipitation adopted by increasing temperature and/or humidity. The leading edge of an advancing colder air mass. Its passage is normally marked by cloud and precipitationhttps://www.sowersoftheword.com followed by a drop in temperature and/or humidity. This image reveals the completely different scales on which snow can happen. The large snow band extending throughout the determine is related to a big storm system transferring throughout the nation.
This picture reveals the reflectivity field from the attention wall of Hurricane Andrew. The symmetry shown in this picture indicates that Andrew was a really properly developed hurricane. The ring of orange are the high reflectivities associated with the convection found in the eye wall.
