(JJAS)

Consistently Warm

Consistently Rainy

1. Eccentricity (more seasonality, 100,000 yrs)

2. Obliquity (more tilt = more seasonality)

3. Precession (wobble of axis)

1. Temporal Scope

-how far can you look back

2.resolution

3. Geographical Coverage

-where it is

strongest at equator

weaker as you move north/south

days = A Lot

Weak = a lot

Decades = not much

Tropical = equator tropics

Mesothermal = florida

Mecrothermal = WI, North

Polar = Poles

Arid = Deserts

Temp

-Latitude

-altitude

-maritime

Precip

-atmosphere moisture

-instability

-prevailing winds

-topography

Strong winds aloft

weak wind low

1. Moisture

-more in humid air

-cold day- warm day- warm humid (50%-100%)

2. Instability

-warm/humid air lower

-cool/dry higher

3. Lift

wind shear

Clear boundary on clouds

Flattening on top

Clouds buldging out

water temps

high humidity

rapid cooling with height

low wind shear

tropics

Warm

-drizzly, grey days

-long cloudy periods

-gentle

Cold

-Abrupt change

-exciting front

-moves fast

Occuled

-thunderstorms

Altitude air rises to and reaches dew point/saturation

3 degrees per 1000 feet

-temperature change in air that is not saturated

-5 degrees per 1000 feet

temperature change in air that is saturated

3 degrees 1000 feet

How much moisture in air relative to how much could be held

land

-solid energy stays put

low specific heat

Water

-moves energy around

-high specific heat

97% ocean

5% fresh

measure of H20

is in the atmosphere

Maratime (slight bump)

Continental (Big bump)
