Exam 12: Middle Latitude Cyclones

The polar jet stream removes air above the surface cyclone and supplies air to the surface anticyclone.​

An upper-level trough that shows retrograde motion would be moving toward the​

When a shortwave disturbs a longwave trough that lies parallel to and directly above a stationary front,the rising of warm air and the sinking of cold air establishes a condition known as ____________________.​

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

If we assume that the absolute vorticity of flowing air is conserved,air moving northeastward will bend ____ to compensate for the ____ in Earth's vorticity.​

In a mid-latitude cyclone,an upper-level pool of cold air that has broken away from the main flow is called a​

Rossby waves are also known as

Vorticity is always present in the atmosphere,even during fair weather.​

The planetary vorticity of an air parcel moving from low toward high latitude in the Northern Hemisphere will​

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

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

Cyclones that normally move northeastward along the Atlantic Coast,bringing high winds and heavy snow or rain to coastal areas,are referred to as ____________________.

If the flow of air into a surface low pressure area is greater than the divergence of air aloft,the surface pressure in the center of the low will​

Vorticity refers to the​

Where maritime arctic air and colder continental arctic air meet,the boundary separating them is called a(n)____________________.​​

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

Divergence and convergence of air are due to changes in

List the mechanisms that provide energy for a cyclone.​

Atmospheric shortwaves usually move ____ longwaves,and ____ when they move through a longwave ridge.​

Jet streaks often occur away from jet streams.​
