EESA09 -2ND LEC.
Four distinct layers in the atmosphere
TROPOSPHERE
STRATOSPHEERE
MESOSPHERE
THERMOSPHERE
What is wind
Movement of air in and ordered fashion
Can we see it??
Not directly but can feel the effects of it
The sound etc..
What causes air to move
Diff in horizontal and vertical air pressure
Pressure gradient
Flow from high pressure to low pressure
Pressure gradient force
Wind primer
Concept of atmospheric pressure
Vert. pressure
Vertical pressure gradient
Horizontal pressure-associated with changes in horizontal flow
Horizontal pressure gradient –which is dominant in the upper
atmosphere
Concept of Atmospheric pressure- what wind do not fall of the surface
level-that is ground
Why all the wind is not moving upward given the fact that air
pressure decreases with height
Gravity vs. PGF (vertical)
Always in balance
Coriolis force
Fictitious force due to the rotation of the earth
Balance between PGF and coriolis
Geostrophic wind
Surface winds
Geostrophic winds is typically 1 km or so above the surface
Below 1 km the wind influenced by friction
Global circulation
One and three cell theories
Seasonality continentality
Upper level flow
Jet streams
Air masses
Board categories of atmospheric circulation

Obv. There is more nrg relased in the poloar region that received from
the sun reverse is true for the equatorial region
One Cell theory
One larger overturning atmpospheric cell
Air rises at the equtor moves poleward and then sinks at the pole
One larger Hadley cell
Named after George Hadkey , brit lawyer and amateur meteorologist (1685-
1768
Atmospheric heat transport
Sensible heat
Heat u can feel
Latent heat
Stored as water vapour
Heat is absorbed when water evaporates
NRG transport
Sensible and latent heat
One cell theory
Rotation intro the coriolis effect
Tilt causes seasonality
Inter-tropical convergence zone area of rising air at or near the equator …
heavy precipitation
Trade winds –winds that blow to the south west, surface component of
Hadley cell
Subtropical high- subsiding air at 30 0 n and 30 0 s –little precipitation,
referred to a the horse latitudes
Westerlies – wind blowing to the eat abd north in the midatitudes –surface
component of the ferrel cell
Polar front –division of polar air
Seasonality – summers and winters
Contientality- land masses heat and cool faster than water
Uses more friction that water
Divergence- moving away from center
Covnergening-coming into the center
Low pressure center-rising air
Higher pressure- clear sunny days
Sinking and rising air
Some highs on ocean some on land
Upper level flow
-why does upper level surface flow?
Think In terms of what do you have at the surface
What you don’t have 1 km from the surface Jet streams
Swift flowing current of air
Thousands of km ling… a few hundred km wide few km thick (10-15 km above the
surface)
