Scales of Motion
Sea breezes and thunderstorms are examples of this scale of atmospheric motion
What is mesoscale?
The one cell circulation model is quite basic, and is missing important features such as this upper level wind pattern that steers surface storms
What is the jet stream?
A geographic area where an air mass develops and acquires its temperature and moisture characteristics is called this
What is a source region?
Cyclogenesis is the process by which these features form at the surface of the atmosphere
What are storms?
This type of front is characterized by it's lack of motion
What is a stationary front?
The jet stream, troughs, and ridges are examples of this scale of atmospheric motion
What is planetary scale?
This atmospheric cell is found from 0 to 30 degrees latitude, and causes heavy rain along the equator and dryness near 30 degrees North and South
What is the Hadley cell?
This air mass typically originates over deserts
What is cT, continental tropical?
These winter storms are fast moving and moisture starved
What are Alberta Clippers?
Foehn, Chinook, and Santa Ana are all different names for this same type of wind system
What are downslope winds?
Wind gusts and dust devils are examples of this scale of atmospheric motion
What is microscale?
This atmospheric cell is found between 60 and 90 degrees latitude, and experiences extreme weather conditions
What is the Polar cell?
This air mass is both cold and humid
What is mP, maritime polar?
What are Nor'Easters?
In the northern hemisphere, winds rotate in this direction around a high pressure system
What is clockwise or anticyclonically?
High and low pressure systems are examples of this scale of atmospheric motion
What is synoptic scale?
This atmospheric cell is found from 30 to 60 degrees latitude, and is responsible for midlatitude weather patterns where we live
What is the Ferrel cell?
This is the coldest airmass that can found on Earth
What is cA, continental arctic?
This type of storm develops from the process of lee cyclogenesis
What are Colorado Lows?
Winds are called this in the Ferrel cell
What are the westerlies?
Weather features considered to be _____ last for the shortest periods of time, and those considered to be _____ last for the longest periods of time
What are microscale and planetary scale?
An important seasonally moving band of heavy shower and storm activity, found between the two Hadley cells, is called this (name or abbreviation accepted)
What is the ITCZ or Intertropical Convergence Zone?
This is the most common airmass experienced in the state of Florida
What is mT, maritime tropical?
The benchmark, or ideal track for a heavy snow Nor'Easter, is located at this specific point (give latitude and longitude please!)
What is 40 degrees North and 70 degrees West?
This theoretical air mass could form over the northern polar regions in the future if the planet continues to warm
What is mA, or maritime Arctic?
