weather

Question 1

humidity

Answer 1

a quantity representing the amount of water vapor in the atmosphere or in a gas.

Question 2

cumulus cloud

Answer 2

Cumulus clouds are clouds which have flat bases and are often described as “puffy”, “cotton-like” or “fluffy” in appearance. Their name derives from the Latin cumulo-, meaning heap or pile

Question 3

startus cloud

Answer 3

Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals

Question 4

cirrus cloud

Answer 4

Cirrus is a genus of high cloud made of ice crystals. Cirrus clouds typically appear delicate and wispy with white strands

Question 5

cumulonimbus cloud

Answer 5

A cumulonimbus is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents

Question 6

condensation

Answer 6

water which collects as droplets on a cold surface when humid air is in contact with it.

Question 7

evaportaion

Answer 7

the process of turning from liquid into vapor.

Question 8

precipitation

Answer 8

rain, snow, sleet, or hail that falls to the ground.

Question 9

runoff

Answer 9

the draining away of water (or substances carried in it) from the surface of an area of land, a building or structure, etc.

Question 10

rain

Answer 10

moisture condensed from the atmosphere that falls visibly in separate drops

Question 11

sleet

Answer 11

a form of precipitation consisting of ice pellets, often mixed with rain or snow.

Question 12

snow

Answer 12

atmospheric water vapor frozen into ice crystals and falling in light white flakes or lying on the ground as a white layer

Question 13

hail

Answer 13

pellets of frozen rain which fall in showers from cumulonimbus clouds.

Question 14

polar maririme airmass

Answer 14

polar air mass, air mass that forms over land or water in the higher latitudes.

Question 15

tropical maritime air mass

Answer 15

Tropical air masses are warm or even hot, as they form within 25 degrees latitude of the equator

Question 16

Continental polar air mass

Answer 16

Continental polar (cP) or continental arctic (cA) air masses are cold, dry, and stable. These air masses originate over northern Canada and Alaska as a result of radiational cooling. They move southward, east of the Rockies into the Plains, then eastward.

Question 17

continental tropical air mass

Answer 17

Continental tropical (cT) air masses are hot, dry, unstable at low levels and generally stable aloft (upper-level ridge) Continental tropical air masses originate in northern Mexico.

Question 18

cold front

Answer 18

the boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system.

Question 19

warm front

Answer 19

the boundary of an advancing mass of warm air, in particular the leading edge of the warm sector of a low-pressure system.

Question 20

lightning

Answer 20

the occurrence of a natural electrical discharge of very short duration and high voltage between a cloud and the ground or within a cloud, accompanied by a bright flash and typically also thunder.

Question 21

thunder

Answer 21

a loud rumbling or crashing noise heard after a lightning flash due to the expansion of rapidly heated air.

Question 22

tornado

Answer 22

a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.

Question 23

hurricane

Answer 23

a storm with a violent wind, in particular a tropical cyclone in the Caribbean.

Question 24

thermometer

Answer 24

an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol that expands and contracts in the tube with heating and cooling.

Question 25

anemometer

Answer 25

an instrument for measuring the speed of the wind, or of any current of gas.
