Science - Weather Flashcards
What are the three stages of a thunderstorm
cumulus, mature, dissipating
What precipitation occurs during the cumulus stage of a thunderstorm
little to no rain
what precipitation occurs during the mature stage of a thunderstorm
heavy rain and hail
what precipitation occurs during the dissipating stage of a thunderstorm
light rain
what causes air masses movement
differences in air pressure
what causes the warm air ahead of a cod front to rise
the cold air is denser and forces the less dense hot air to rise
what kind of clouds usually form in a cold front
towering cumulus and cumulonimbus
what wind direction change usually occurs as a cold front moves through and area
southwest to northwest
where do vertical shear winds form
at the front of a cold front
what kind of weather is usually expected in a cold front
stormy and sometimes severe
what cloud types are typically associated with a warm front
stratus and nimbostratus
which air mass provides the moisture that produces the clouds and precipitation
warm fronts
what severe events could warm fronts produce
blizzards and flooding
what kind of weather is usually expected in a warm front
overcast skies and steady precipitation
what do red half circles indicate on a weather map
warm front
what do blue triangles indicate on a weather map
cold front
our weather is made up of 5 combinations of . . .
temperature, humidity, cloud cover, wind, precipitation
what are the three ways heat can move
radiation, conduction, convection
what is heat
the transfer of energy from one substance to another
what is the transfer of heat by electromagnetic waves
radiation
what is the transfer of heat from one object to another through direct contact
conduction
what is the transfer of heat through moving liquids, fluids, or gasses through currents
convection
the strength and amount of heat we get depends on what
tilted axis and seasons
what is temperature
a measure of how much energy is in a substance’s molecules
