The piling up of air above a region is called​

Earth's vorticity can be positive or negative in the middle and high latitudes, depending on the hemisphere.​

In a mid-latitude cyclone, the warm sector is located​

Lee-side lows are​

Like hurricanes, polar lows have a clear area in their center.​

The development of a mid-latitude cyclone, according to the Norwegian model, begins along the​

Another term for explosive cyclogenesis used by meteorologists is​

Atmospheric shortwaves usually move ____ at a speed that is ____ than longwaves.​

Which statement about vorticity is least accurate?​

In general, at the 500-mb level, the vorticity maximum and the shortwave move along at about ____________________ the speed of the wind.​

​Which of the following is associated with rising air motions in a mid-latitude cyclone?

Developing low pressure areas in mid-latitude cyclones generally have ____________________ air near the surface and ____________________ air aloft.

​Storms that form over polar water behind (or poleward of) the main polar front are called

With diameters of ____ or less, polar lows are generally smaller in size than their mid-latitude cousins.​

List the mechanisms that provide energy for a cyclone.​

Which scientist helped develop the polar front theory of a developing wave cyclone?​

Mid-latitude cyclones usually "die out" after they become occluded because there is no longer a temperature contrast at the surface.​
