Weather
What layer of the atmosphere does all weather take place?
Troposphere
List two greenhouse gasses
Carbon dioxide, ozone, water vapor, CFC, methane, nitrous oxide
What is an air mass?
a large body of air with uniform temperature and moisture
What is a station model?
A symbol showing current weather conditions
What effect does latitude have on climate?
closer to the equator is warmer, further away is cooler
What causes weather?
Unequal heating of earth's surface
List 5 factors that affect climate
What does mT stand for?
maritime tropical
What type of air mass will most likely form over the pacific ocean, north of the Aleutian trench?
mP (maritime polar)
Why does water moderate temperature?
Because water has a high specific heat
Describe how a cloud is formed
air rises, expands and cools to the DP
Condensation occurs, which is cloud formation
How does air movement at the pressure belts affect climate? (Air rising vs air sinking)
air rising produces clouds and a humid climate
air sinking does not produce clouds, results in a dry climate
What pressure center are fronts always attached to?
How does the air circulate around that pressure center?
Low pressure, counterclockwise rotation
What planetary wind belt is the united states located in?
What direction do all storms track in the united states?
Wind belt: South Westerlies (SW)
Storm direction: Eastward or North East
On the board, draw the cross section of a cold front
Ms. Karban will judge
Is energy gained or released from 2 grams of ice melting? How much?
gained, 668 J
On the board, draw the orographic effect.
Label both sides with the name and climate (temp and moisture)
Windward:cool and wet
leeward:warm and dry
On the board, draw a cold front and a warm front.
Label the air masses behind each front
Ms. Karban will judge the drawing
On the board draw a station model with the following characteristics:
temp:31 F
DP:29 F
Snow
pressure: 999.5 mb
Wind speed: 30 knots
wind direction: NW
Ms. Karban will judge the picture
List the weather device that measures the following atmospheric conditions: temperature, DP, RH, amount of precipitation, pressure, wind speed, wind direction
thermometer, sling psychrometer, rain gauge, barometer, anemometer, wind vane
Name the weather instrument that measure DP and RH.
What is the wet bulb temperature if the DP is 15C and the DB is 18C?
16 C
Describe where an el nino and la nina event occur.
What are the water and wind conditions during an el nino and la nina?
El nino is the warm phase from weak trade winds
La nina is the cool phase from strong trade winds
Draw on the board a Low pressure center with an occluded, warm and cold front.
Ms. Karban will judge the drawing
air temp and dew point are close together
100% cloud cover
low pressure
What layer of the atmosphere contains ozone?
What layer of the atmosphere does weather occur in?
What layer of the atmosphere do meteors burn up in?
stratosphere, troposphere, mesosphere
