El Nino, La Nina, and the Southern Oscillation
Polar Jet Stream
Strongest temperature gradient typically found on cold side of polar
front
Yields strong height (pressure) gradients aloft, especially near
tropopause
o Temperature gradient strongest in wint
General Circulation and the Jet Stream
The General Circulation
Think of the atmosphere as a river
o Individual weather systems in the atmosphere are like turbulent
eddies in a river
o Average these out and you will see the general flow of the river

MidLatitude Cyclones: Weather
What is a midlatitude cyclone?
Also called an extratropical cyclone
o An area of surface low pressure
o Requires upperlevel low/trough (at 300500 mb level) to form
Any cyclone is an area of low pressure
o Center of cyclon
MidLatitude Cyclones: Life Cycles
Stages:
Frontal wave (initial development)
Open wave (cyclone strengthens)
Cyclogenesis:
Development (birth) of midlatitude cyclone
There are favored regions for cyclogenesis
o East of mountain ranges (e.g. the Rockies)

Clouds & Precipitation
Review:
Saturation:
o Microscopic balance between evaporation & condensation
o Saturated vapor content increases with temperature
Measures of water vapor content in air:
o Water vapor pressure
o Relative humidity
Dewpoint Temperatur
Upper Level and Surface Winds
Review
Constant pressure maps describe upper atmosphere
o Contours of height of constant pressure surface plotted
o High heights indicate warm air below & are analogous to high pressure
o

Seasonal and Daily Temperatures
Review
Air Parcels
o Air warmer than surroundings rises (less dense)
o Rising air parcels cool; sinking air parcels warm
Radiation & Greenhouse Effect
o All items emit & absorb radiation
o Warmer objects emit more radiation
On average, the earth is 150 million km or 93 million miles away from
the sun
At its surface, the earth maintains an average temperature of about 15
degrees C or 59 degrees F
The lowest temperatures can drop below 85 degrees C or 121
degrees F

Review:
Pressure is caused by weight of air above you (force per unit area)
o Always decreases with height
o Varies more in vertical than horizontal
o Correct to sealevel pressure for surface maps
