15
Q

drybulb

A

air temperature

16
Q

wet bulb

A

usually lower because of evaporation

17
Q

air pressure

A

weight of air around you

18
Q

lower air pressure at

A

high altitude

19
Q

normal air pressure

A

1 atmosphere
1013.2 mb
29.92 inches of mercury
14.7 PSI

20
Q

a cloud is made of

A

water droplets or ice crystals

21
Q

cloud recpie

A

1- water vapor
2-cooled to the dew point –> condensation
3- surface to condense on … tiny particles of smoke, dust = condensation nuclei

22
Q

adiabatic cooling

A

air rises , expands and cools down

23
Q

wind

24
wind is caused by
a difference in air pressure from high to low pressure always
25
fastest winda
big difference in air pressure steep pressure gradient where isobars are closely placed together
