- Heat
- a form of energy that flows between objects of differing temperatures
- sensible heat
- the heat we can feel and measure with a thermometer
- latent heat
- the energy absorbed or released during a change in state
- Principle temperature control
- latitude, altitude, and continentality
- continentality
- the effect of the distance from the ocean on the climate
- specific heat
- amount of heat required to increase the temperature of water
- transparency
- permitting the free passage of electromagnetic radiation
- maritime
- moderate temperatures
- continental areas
- more extreme temperatures
- climographs
- Line is temperature, bars are precipitation.
- atmospheric circulation
- transportation of matter and energy
- levels of atmospheric circulation
- primary: large scale global circulation trends secondary: migrating high and low pressure systems Tertiary: local winds and weather
- wind basics
- horizontal motion of air
- Winds coming from the west is?
- westerlies winds
- Winds coming from the east?
- Easterly winds
- pressure gradient force
- areas of higher or lower barometric pressure cause winds
- coriolois force
- deflects wind from a straight path in relation to earth's rotating surface
- friction force
- drags on wind as it moves across the surface
- lateral differences in air pressure is caused by
- differences in temperature and dynamic atmospheric forces
- isobar
- A line connecting two points of equal pressure.
- what causes air current?
- high pressure areas you see DESCENDING AIR and in low areas you see ASCENDING air
- geostrophic winds
- a wind moving between areas of different pressure along a path that is parallel to the isobars.
- cyclones
- low pressure counterclockwise
- anticyclones
- high pressure clockwise
- tropical cyclones
- huge rotating masses of low pressure characterized by strong wonds and torrential rain
- land breeze
- the flow of air from land to a body of water
- sea breeze
- a cooling breeze from the sea (during the daytime)
- asian monsoon
- A seasonal reversal of winds; a general onshore movement in summer and a general offshore flow in winter, with a very distinctive season precipitation regime.
