24
Q

Genesis

A

Formation/intensification

25
Cyclogenesis
Formation/deepening of a low center
26
Anticyclogenesis
Deepening or forming a high
27
Frontogenesis
Increasing contrast of a front
28
Olysis
Dissipation of a weather feature
29
Cyclolysis
Dissapate a low
30
Anticyclosis
Dissapate a high
31
Frontolysis
Dissapate of a front
32

Petterssens rule
Cyclogenesis occurs when divergence aloft is over a weak surface
41
Cold Occlusion
East Coast between triple point and wave cyclonic Weather-stratified clouds(stable) Continuous precip Behind front there is westerly winds.Ahead of front south easterly Dew point :cold behind/warm in front Temp gradually cools Surface winds:veer horizontally Pressure:rise gradually
42
Warm Occlusion
West coast between triple point and wave cyclone Weather: stratified clouds(stable) Continuous precip Behind :westerly winds Ahead :Southeasterly wind sfc:veer horizontally Pressure rises gradually Temp: cold behind,colder ahead Dew point moist behind/dry ahead
43
Active Cold Front
Sudden temp drop,then gradual cool Dew points drop slowly Surface winds veer horizontally Pressure rises steadily
44
Inactive Cold front
Temps slowly become colder Dew points drop sharply Sfc winds veer horizontally Pressure rises slightly followed by a sharp fall
