Unit 6 Hurricanes

80 mcqs on final exam

As a northward moving hurricane passes to the east of an area, describe how to hurricane winds are going to change as the hurricane moves south to north

Winds shift from southeast to southwest to northwest.

tropical systems are given a name once they ____

have winds that reach 39 mph and become a tropical storm

the large thermal cell driven by convection hot towers along the equator is the ____

the hadley cell

winds along the equator that are weak and variable are called

horse latitudes

el nino is a result of the cyclical weakening of the ____

easterly trade winds

a hurricane travels eastward toward the Florida peninsula from the Gulf of Mexico which side of the storm would present the strongest winds?

n/s/w/e

east???

most hurricane deaths are a result of __

water- flooding from storm surge and torrential rains

the strongest winds of a hurricane can be found ____

on the right front quadrant of the eye wall

the vertical structure of a hurricane shows upper level ___ of air and surface ___ of air

upper level outflow of air and surface in flow of air

following the three cell model of regions where would one expect to find regions of surface low/high pressure

the equatorial lows (doldrums)

subtropical highs

subpolar lows

polar highs

assuming air temperature stays constant, evaporating water will cause ____ to happen to dew point and ___ to happen to relative humidity

the dewpoint to increase the relative humidity to increase

surface divergence of the Ferrell cell and Hadley cell around 30 degrees latitude what will happen at that band (what is at 30 degrees latitude around the world)

air sinks and creates high pressure zones with dry, stable conditions, leading to calm winds and the world’s major deserts.

based on Florida avg latitude of 26-30 degrees what it is prevailing surface wind direction

a tropical storm with 50 mph winds would be classified as

a tropical storm.

as they travel west and northwest through the Caribbean the tropical systems often curve toward the north and northeast. Why does this occur? choose all that apply

during which phase of a mid latitude cyclone is the cyclone at its most intense

the mature stage

the processes of freezing and condensation release____

latent heat

what air mass originates over the gulf or atlantic ocean

maritime tropical

wind shear associated with multiple airline crashes is called ____

downbursts or microbursts

which type of imagery is not at all able to indicate the presence of clouds

water vapor imagery

what is a common limitation of radar

outgoing long wave /terrestrial radiation from the earth is primarily blank ____

Infrared/heat radiation

the pressure gradient force is directed ____

from areas of higher pressure to areas of lower pressure

which hydrologic process releases energy in the form of latent heat

Condensation and freezing
