Tempurature And Heating Flashcards
What is the average kinetic energy of an atom or molecule?
Temperature.
Celcius = ( F - 32 ) x fraction
5/9
What does a stevenson screen measure?
Surface air temperature.
How high is a Stevenson screen above the ground?
1.2m or 4 ft
A radiosonde climbs to 35km and measure three things at 1.3 second intervals.
Temperature / pressure / humidity.
What does it mean if radiation has shorter wavelength in regards to intensity?
Hotter the object or more intense.
What does the acronym silo mean in regards to radiation?
Shortwave in longwave out.
When is the hottest time of the day?
3pm.
What part of the day is it the coldest?
An hour after sunrise.
What is earth insolation?
Sun heating the earths surface.
What is Perihelion on the 4th of jan?
When sun is closest to the earth.
What is aphelion on the 4th of july?
Earth is furthest from the sun.
What is the ITCZ?
A band of low pressure.
What percentage of solar radiation reaches the earths surface?
85%.
What causes scattering of solar radiation?
Atmospheric particles.
What is albedo?
Surface reflectivity.
What is the earths average albedo as percentage?
31%.
Energy transfer from advection is what direction of movement?
Horizontal movement.
Condensation releases what type of heat?
Latent.
What is the heat energy required to make a change in state?
Latent heat.
What is diurnal variation?
The variation in surface tempurature.
Will cloud cover result in colder or warmer minimum?
Warmer minimum.
If it is windy at night, is the temperature going to be higher or lower than normal?
Higher.
An inversion is a layer of air in which tempurature increases with blank.
Height.
What type of air is at the bottom of a valley?
Cooler air.
What is a katabatic wind?
Winds coming down mountains due to it cooling.
Why does fog form in valleys?
Cooler air cannot hold onto moisture very well.
What does a cold front bring when it meets tropical air?
CB or thunderstorms.
What weather happens in a warm front when it meets a cooler front?
Drizzle or rain.
A subsidence inversion see you travel from what temperature to what temperature?
Cool to warm.
What is a wind shear?
Reduction in air density.
What are the primary factors driving heat transfer from the ground to the lower levels of the atmosphere?
Conduction and turbulence.
