Don't Get Blown Away
The atmospheric scale associated with Land and Sea Breezes.
What is Mesoscale?
A single-cell, thermal circulation model of atmospheric circulation that can be observed between 0 and 30 N/S latitudes.
What is a Hadley Cell?
Named after the Christ child because the phenomenon occurred during December, this event sees the abnormal warming of waters at the Equator and along the West Coast of S. America.
What is El Nino?
Symbolized by a red line with half-circles, this front type generally brings winds from the South.
What is a Warm Front?
In the Northern Hemisphere, this has surface winds that diverge and rotate clockwise.
What is an Anticyclone?
These winds are cold and dense. They flow, by gravity, down slope.
What are Katabatic Winds?
Global area of converging trade winds where air rises. It can often be identified by satellite imagery due to a band of cloud cover that circumnavigates the Earth.
What is the Intertropical Convergence Zone (ITCZ)?
The abnormal cooling of sea surface temperatures along the Equator and West Coast of S. America.
What is La Nina?
Heavy showers of rain or snow, sometimes with hail, thunder and lightning are associated with the passage of this type of front.
What is a Cold Front?
Series of waves with ridges and troughs in upper atmosphere westerly winds.
What are Rossby Waves?
Large, towering walls of sand and dust carried by strong winds. Woody Guthrie sang about one of these he experienced on April 14, 1935.
What are Haboobs or Black Blizzards?
Semi-permanent areas of high pressure that are located approximately 30 degrees North or South of the Equator.
What are Subtropical Highs?
Seesaw pattern of reversing surface air pressure at opposite ends of the Pacific Ocean.
What is the Southern Oscillation?
This boundary tends to move East during the day and West at night. It originates in West Texas, OK or Kansas in the spring and early summers. Dew Points are the key to locating where this boundary is.
What is the Dry Line or Dew Point Front?
In the upper atmosphere the process where wind speeds speed up as they emerge from a trough.
What is Speed Divergence or Diffluence?
Differential heating between seasons over continental and oceanic regions that results in winds that change direction. The result is a pronounced dry and wet season.
What are monsoons?
The boundary between cold, polar air and warmer, moist air located approximately at 60 degrees North Latitude. It is responsible for weather patterns in the US.
What is the Polar Front?
What are the Tradewinds?
Type of front where the cold sector catches up and overruns the warm sector causing the warm air to be lifted aloft.
What is an Occluded Front?
Process where cold air moves down the temperature gradient and crosses isotherms on an isobaric chart.
What is Cold Advection?
This force is responsible for winds to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
What is the Coriolis Effect? or Coriolis Force?
Strong, upper atmospheric winds that flow from the West to the East around the Earth.
What is the Jet Stream?
The boundary layer between warm, surface ocean water with colder, more nutrient filled waters from the ocean floor.
What is the Thermocline?
The stage of Cyclogenisis where occlusion begins.
What is the Mature Stage?
The location where a Mid-Latitude Cyclone develops relative to an upper atmospheric trough.
What is to the right side?
What is East of the trough?
What is where upper air divergence occurs?
