Which region is not considered to be a region where cyclogenesis often occurs

California.

The development or strengthening of a middle latitude storm system is called

cyclogenesis.

According to the model of the life cycle of a wave cyclone, the storm system is normally most intense

when the system first becomes occluded.

On a surface weather map that shows an open wave cyclone the warm sector can be observed

ahead of an advancing cold front.

Atmospheric shortwaves usually move at what speed and what length compared to longwaves

west to east, faster.

If the outflow of air around a surface high pressure area is greater than the convergence of air aloft, you would observe

a decrease in the central pressure.

Developing low pressure areas generally have

converging air near the surface and diverging air aloft.

For a surface storm system to intensify, the upper-level low(or trough) should be located

west of the surface low.

When an upper-level low lies directly above a surface low

the surface low will probably weaken.

A surface low pressure area with deep upper-level trough to the west will tend to move toward the

northeast.

For cyclogenesis to occur along a frontal wave, the winds aloft directly above the wave should be

diverging.
