key conceptw of heat transfer
what is conduction?
Transfers heat throught direct contact
What is earths main heat source and what does it affect?
Solar radiation and it affects climate and weather
Define nibmostarus clouds
bring steady precipitation and r usally gray and cover the sky
what does lighting begin with
it begins with a stepped ladder (faint intial discharge)
what are fronts
boundaries bettween airmasses coldee denser air usally pushes under warmer air
what is convection?
Transfers heat by movement within fluids: responsible for ocean and air currents
how does wind form and how does it move?
pressure differences and from high to low pressure
how does sleet form
When rain falls throught a freezing layer of air
whats a return stroke
the bright flash we see
define a low pressure system
involves rising air and often causes clouds and storms
What is Radiation?
Heat transfer through electromagnetic waves: does not require a medium
Where do polar easterlies occur and at what temp do they meet warmer westerlies
define continental tropical
air masses that are hot and dry and form over deserts
what are radiosondes
balloon-borne instruments mesuring atmospheric Data ( temp, pressure, and humidity)
define high pressure systems
bring cooler, drier air and clear skies
Heat vs tempature
Heat is energy in transfer: Tempature means average molecular energy
what are chinook winds
dry, warm winds decending mountain slopes, rasing tempatures rapidly
define cloud seeding and what it does
it uses substances like dry ice to encorage rain in drought-prone areas
what do blizards involve
true or false seasons are due to the disance from the sun
false- seasons are due from earths tilt and revolution
Whats an Isobar
A line on a weather map conecting areas of equal air pressure
whats the tropospere
closest to the earth, weather occurs here, temp decreases with altitude
whats the stratosphere
contains the ozone layer, temp increases with altitude due to uv absorbtion
whats the mesosphere
coldest layer, metors burn up here
whats the thermosphere
very thin air, temp increases with solar activity
