1. Radar Palette Home Click Doppler Warm Sector 1 Ahead of WCB within the Warm Sector These conceptual models will be virtually identical to those associated with the three locations north of the warm front with the exceptions that: There will be and cannot be any evidence of the cold conveyor belt The veering and backing with height signatures will be less pronounced The reduced extent of warm sector precipitation will be an issue Gulls are found in the warm sector, more so than eagles… Click for the Conceptual Model and Explanation

This is a straight line uniform wind field but could be a slightly divergent signature. Right Wing Left Wing Note that headless gulls can’t scream… The advections in the warm sector do not warrant this being called an eagle pattern.

Note the A line is “sharper “ looking than B. C to D represents a low level jet max. Notice that outward from A and B and the inflexions the lines of constant radial velocity are nearly parallel( except for some slight backing from B to G) to the radials indicating constant wind direction. We see a higher level jet max from E to F.

The links to the three sections of the airflows that comprise each of the conveyor belts are located at Slide 1,11 and 21. Slide 11 is always the central, col limited circulation. This leaves 10 PowerPoint slides for the development of the training material which should be more than adequate.
