Question 6

what is the unit that we use for weather stuff that starts with a J

Answer 6

joules

Question 7

why is it colder when their is wind? what is the effect

Answer 7

because the wind blows the air surrounding us and makes it cold. the wind chill effect

Question 8

describe condensation process

Answer 8

water vapor molecules in warm air move fast. the molecules dont come together and condense well. but as air cools osme molecules move closer and join allowing condensation to happen.

Question 9

what is relative humididty

Answer 9

the measure of amount of water vapor in air, compared to what it could hold

Question 10

does cold or warm air hold more water

Answer 10

warm air

Question 11

what is saturation

Answer 11

it is when enough water vapor is present in the air for condensation

Question 12

what is dewpoint

Answer 12

the temp at which air is saturated and condensation happens.

Question 13

what is the tool that measures relative humidity

Answer 13

psychrometer.

Question 14

what is adiabatic temperature changes

Answer 14

its the temperature change that occurs without being added or removed

Question 15

what is the rate of cooling the higher your are in the atmosphere

Answer 15

10 celcius every 1000 meters: the opposite is know as dry adiabatic rate

Question 16

what is frontal wedging

Answer 16

cold air comes and pushes warm air up

Question 17

what are convergences

Answer 17

hot air rises then cools to dew point

Question 18

what is orographic lifting

Answer 18

it is when mountains act as a barrier and force air over

Question 19

what is localized convective lifting

Answer 19

occurs where unequal surface heating causes pockets of air to rise

Question 20

what is needed for percipitation

Answer 20

nuclei,

Question 21

what are cirrus clouds

Answer 21

fluffy clouds at high elevation

Question 22

what are stratus clouds

Answer 22

the clouds that are like a veil and cover up the sky

Question 23

what are cumulus clouds

Answer 23

the puffy ones that look like cotton balls

Question 24

what are the two ways clouds are classified

Answer 24

by their height and form

Question 25

Answer 25

high- cirrus 6000m
middle-alto 4000m
low-strato 2000m

Question 26
