HW 5: Ch. 6 Air-Sea Interactions
10 pts total; 1 pt each question
1.
What causes the Earth’s seasons? How is a solstice different from an equinox? For the start of
each season, state whether it is a solstice or an equinox.
- Seasons are caused by tilt of the Earth's axis . Solstice reaches the sun at its mostly northern or
southerly point while an equinox means the sun is directly above the equator.
-
Summer solstice , Spring Equinox , Fall Equinox , Winter solstice
2.
Describe how wind forms in a convection cell. In your answer, include what happens to warm and
cool air, where low and high pressures form, and the direction of wind relative to pressure.
-
Rising and cooling air moving in a circular fashion creates a wind , An area of high pressure is
caused by cool sinking air. Warm air ascending creates an area of low pressure ,Wind is always
produced when air shifts from high to low pressure.
3.
How does the Coriolis effect differ in the Northern vs Southern Hemispheres? If a plane is
traveling south in the Northern hemisphere, what direction (north, south, east, or west) will it be
deflected? -
- in the Northern Hemisphere, everything bends right Objects in the Southern Hemisphere bend to the
left.
- South
4.
Describe how a Hadley cell forms in global atmospheric circulation. Include where low and high
pressure occur. Relate how this pressure results in trade winds.
Warm air rising near the equator drops approximately 30°N/S.
The Hadley cell is a type of convection cell found at higher latitudes, similar to Ferrel and polar cells.
High pressure is where cool air sinks where low pressure is where warm air rises. This pressure results in
trade winds because , a low-pressure area forms at the surface as warm air rising toward the equator
5.
Contrast the rotation of winds in a high pressure vs low pressure system. What weather conditions
are typical in areas of high pressure? What weather conditions are typical in areas of low pressure?
High pressure occurs when chilly air descends. Polar highs are found at the poles, while subtropical highs
are found between 30°N and S. There is brilliant sky and dry air as you descend. Low pressure causes
warm air to rise. An equatorial low is the equator. S and 60°N represent subpolar lows. overcast with a lot
of precipitation.
6.
Explain the convection currents of a sea breeze along the coast. In your answer, include where air
rises and falls, where high and low pressure is located, and the direction of wind.
As a result of the ocean's high specific heat and the land's uneven heating and cooling, convection
currents of a sea breeze form along the shore. A zone of low pressure is created when warmer air on land
rises. From high to low pressure, cooler air over the ocean moves in the direction of land.
7.
What 2 conditions are needed for hurricane development?
-
Warm Water (supply energy)
-
. Rotational factor to circulate air around center
8.
Describe the rotation of hurricanes in the northern hemisphere versus southern hemisphere. Why
does the rotation differ between hemispheres?
-
In accordance with Coriolis, wind in the northern hemisphere is directed toward areas of low
pressure and to the right. rotation in the S. Hemisphere clockwise due to Coriolis's leftward air
deflection The Coriolis effect, which is a product of the Earth's rotation, causes the rotation of the
Earth to differ between the Northern and Southern Hemispheres.
9.
What are the 3 parts of a hurricane? Where are the winds calm, and where are the strongest winds
located?
-
Parts of the Hurricane Eye , Eye Wall , Spiral rain bands
-
The wind calms the in Eyes of the hurricane center .
-
The eye wall is where the strongest winds are while the worst part of the hurricane as well.
10. What is a storm surge? Besides storm surge, what are 3 other hazards of hurricanes?
-
ocean's flow onto land during a storm that's a storm surge .
-
3 other hazards of hurricanes
-
Tornados & lightning , Heavy rains – flooding , Strong winds
