meterology
our atmosphere and weather
trophosphere
all weather
tropopause
top of trophosphere
stratosphere
ozone layer
stratopause
top of the stratosphere
the 4 layers are based on
temperature trends
moisture absorbent gas
nitrogen
weather station models
description of current weather
barometric pressure conversion
put a 9 in front and a decimal
put a 10 in front and a decimal
closer to 1,000 mb wins
storms typically move across the USA to the northeast because
we are in the southeast windbelt
southeast windbelt
prevailing from southwest to northeast
warm air holds more
water vapor
cold air is
dry air
dewpoint
temperature at wh ich air is saturated
relative humidity
percentage of saturation
drybulb
air temperature
wet bulb
usually lower because of evaporation
air pressure
weight of air around you
lower air pressure at
high altitude
normal air pressure
1 atmosphere
1013.2 mb
29.92 inches of mercury
14.7 PSI
a cloud is made of
water droplets or ice crystals
cloud recpie
1- water vapor
2-cooled to the dew point –> condensation
3- surface to condense on … tiny particles of smoke, dust = condensation nuclei
adiabatic cooling
air rises , expands and cools down
wind
moving air
