weather

current atmospheric conditions at a particular place and time

trees where you can see the direction in which the wind was blowing?

flag form

why is ozone important?

it blocks out UV radiation because UV radiation damages nucleic acids

downwind side

leeward side

in the southern hemisphere, winds deflect to the

left

climate

long term weather trends of a particular region

high winds and ozone occur in what layer of the atmosphere

lower stratosphere

why is wind chill factor important?

maintains temperature gradient

what is the climate gradient of the east and west

moisture

deflective currents

mountains - winds coming up on both sides

what processes direct air flow?

(TVDIS) thermal valley deflective currents inversion sea breeze

wet adiabatic lapse rate

0.6°C/100m rise - the rate at which a saturated body of air cools as it lifts - how much water cools down as it is condensing into water droplets

biological importance of wind

1. wind chill factor 2. krummholz effect 3. seed and pollen dispersal 4. flying/migratory routes for birds and mammals

dry adiabatic lapse rate

1°C /100m rise - The rate at which the temperature of a parcel of dry air decreases as the parcel is lifted in the atmosphere.

what are the components of the atmosphere

Nitrogen Oxygen Argon CO2

Coriolis effect

The effect of Earth's rotation on the direction of winds and currents.

valley breeze

The movement of air created by warm air rising and flowing up the slope of a mountain.

orographic precipitation

precipitation that develops when warm, moist air cools and condenses as it rises against mountains

a consequence of the Coriolis effect

predicting storms

in the northern hemisphere, winds deflect to the

right

layer atop the troposphere

stratosphere

what is the climate gradient of the north and south

temperature

inversions

the densest air is near the ground - moisture and pollutants are trapped preventing heating near the surface - stable

adiabatic lapse rate

the idea that air will change temperature if forced to move up or down an atmosphere

Krumholtz effect

trees tend to be stunted in very windy areas

what causes circular ocean currents?

tropical heating, surface winds and the Coriolis effect

where do jetstreams/sheer zones/storm anvils occur?

tropopause

in what layer of the atmosphere does weather occur?

troposphere

what layer of the atmosphere is closest to the ground?

troposphere

sea breeze

type of thermal breeze - high specific heat of water, low temp change

side receiving wind

windward side
