Front 1

the subpolar point is defined as

Back 1

the point on earth's surface where solar rays arrive perpendicular to the surface

Front 2

the solstice is

Back 2

the time of year when the subsolar point is farthest from the equator

Front 3

the equinox is

Back 3

the time of year when the hours of sunlight and darkness are equal everywhere on earth

Front 4

it is the time of the equinox when

Back 4

the point where the subsolar point is directly above the equator

Front 5

the position of the subsolar point is confined to the latitudes between

Back 5

23 1/2 degrees N/S

Front 6

when the subsolar point reaches the tropic of capticorn

Back 6

it is summer in the northern hemisphere

Front 7

incoming radiation from the sun

Back 7

is shortwave radiation

Front 8

earth genereally emits radiation that is

Back 8

longer wavelength than the Sun's emissions

Front 9

counter-radiation of longwave energy in Earth's atmosphere is primarily due to

Back 9

the presence of water vapor and carbon dioxide in the atmosphere

Front 10

sensible heat is

Back 10

energy in the form of temperature

Front 11

latent heat is

Back 11

energy stored in evaporated water

Front 12

the average daily temperature is typically lower at Savannah, GA than at Las Cruces, NM because

Back 12

more of the energy budget is contributing to latent heating at Savannah

Front 13

the term "continentality" describes

Back 13

climate affected by greater temperature ranges

Front 14

an air mass is defined as

Back 14

a large body of air having relatively uniform humidity and temperature characteristics

Front 15

the general rule for air parcel moisture content is

Back 15

warmer air can hold more moisture and colder air holds less moisture

Front 16

a saturated air parcel

Back 16

is at 100% relative humidity

Front 17

relative humidity measures

Back 17

the amount of water in the air relative to the potential amount of water the air can hold

Front 18

adiabatic heating or cooling is the result of

Back 18

vertical motions in the atmosphere

Front 19

adiabatic cooling is the result of

Back 19

decreasing air pressure

Front 20

the wet adiabatic lapse rate is less than the dry rate because

Back 20

latent heat energy is released during condensation (becomes sensible heat)

Front 21

an air parcel that is rising and cooling at the dry adiabatic lapse rate may eventually cool at the wet adiabatic lapse rate if

Back 21

it reaches the dew point temperature

Front 22

as an air parcel rises up a mountainside

Back 22

it cools adiabatically because pressure decreases

Front 23

what provides the driving energy for atmospheric circulation and gets it moving in the first place

Back 23

the energy surplus accumulates in the tropics

Front 24

Hadley Cell convectional circulation is initiated by

Back 24

atmospheric heating near the subsolar point

Front 25

regions dominated by rising air in the Hadley Cells tend to be

Back 25

wet because the rising air enhances precipiation

Front 26

regions dominated by sinking air in the subtropical highs tend to be

Back 26

dry most of the year

Front 27

the westerly winds are created by a combination of

Back 27

a combination of the thermal convection, the pressure gradient force, and the coriolis force

Front 28

climates that have a yearly wet/dry cycles are caused by

Back 28

shifting of the hadley cells under the subsolar point

Front 29

the dominance of the asian low over India results in

Back 29

summer monsoonal circulation

Front 30

the monsoon of the southwestern united states commonly originates from

Back 30

flow of the Sonoran Jet

Front 31

the energy for hurrican formation comes from

Back 31

warm ocean waters

Front 32

some hurricanes in the western Atlantic Ocean originate as

Back 32

thunderstorms over west africa
