5 air masses
What are the two source regions of the five air masses?
What are continental and maritime
What is a cold front ?
What is a boundary between cold dry air and warm moist air in which the cold dry air is replacing the warm moist air
What does enso stand for?
El Nino Southern Oscillation
What is the red line indicating?
Temperature
What temp scale do we use for surface level plots?
Farenheit
What type of air mass is cool, moist, and unstable?
What is a maritime polar air mass
What is a dry line?
sharp boundary between two air masses w/ different moisture characters
What is every 10-30 years
Which value is the log value?
Pressure
what is the 3 hour difference
What describes a continental tropical air mass?
hot, dry, stable air aloft, unstable surface air
What is a warm front passage marked by?
What is it called when the normal pattern is enhanced?
La nina
What axis does dew point come from?
x
How many mph is 1 knot
1.15 mph
Describe a continental arctic air mass?
extremely cold, dry, stable, ice and snow covered surface
What is it called when two air masses are beside each other but neither is moving appreciably
quasi stationary front
What is the non el nino setup
L in w pacific
high in e pacific
north of equator, e wind, water flows north (CF acts to the right)
water vacates at equator, more upewelling
What line do you follow for a saturated parcel?
Moist adiabatic
How many m/s is one knot?
.5 m/s
Which air mass is warm, moist and unstable?
What is maritime tropical
What is an occluded front?
Result of a cold front interacting with a warm front ( catching up to)
What happens globally when el nino is occurring>
warmer global T, disrupts precip patterns, floods nad droughts, fewer atlantic hurricanes, warmer e coast winters
What do we follow the dry adiabatic line until?
Until the parcel is saturated, at a level where dry adiabatic intersects r
What is the lower left hand value on an upper air station plot
