|---|---|---|---|---|---|
| weather | the conditions of atmosphere at a given location for a short period of time
🗑
|
||||
| climate | the characteristic weather that prevails from season to season and year to year
🗑
|
||||
| air temperature | measures how much kinetic energy the air molecules have
🗑
|
||||
| air pressure | caused by the weight of atmosphere pushing down
🗑
|
||||
| wind | the horizontal movement of air caused by differences in pressure
🗑
|
||||
| humidity | moisture content of the atmosphere
🗑
|
||||
| what is weather caused by? | the unequal heating of earth's surface, resulting in the formation of convection currents in our atmosphere
🗑
|
||||
| in what layer of our atmosphere does weather occur? | troposphere
🗑
|
||||
| how does an air mass form? | in our atmosphere, when air remains nearly stationary over a large section of earth's surface and takes condition of temperature and humidity from that location
🗑
|
||||
| what causes air masses to move? | planetary wind belts
🗑
|
||||
| what is a front? | boundaries between air masses, precipitation is likely to occur at these boundaries
🗑
|
||||
| high pressure system | pleasant, sunny, clear weather, not cloudy or rainy, could happen in any season. wind moves clockwise, out and down
🗑
|
||||
| low pressure system | lousy, cloudy, stormy weather, and depending on the season, could happen in any season. wind moves counterclockwise, in and up
🗑
|
||||
| in the United States, which way do high and low pressure systems move? | the general movement is from west to east because of the prevailing westerly wind belt
🗑
|
||||
| what is the difference between weather and climate? | weather is the daily atmospheric conditions for a specific location at a specific moment in time, climate is the average atmospheric conditions for a location over the course fo many months or years
🗑
|
||||
| what are the layers of the atmosphere (in ascending order)? | troposphere, stratosphere, mesosphere, ionosphere
🗑
|
||||
| what relationship does altitude and pressure have? altitude and temperature? | indirect, indirect
🗑
|
||||
| what is atmospheric pressure affected by? | water vapor
🗑
|
||||
| water vapor is light compared to what? | dry air
🗑
|
||||
| what is the relationship between pressure and humidity? | indirect
🗑
|
||||
| dew point temperature | temperature at which the air is holding the maximum amount of water, the air is saturated
🗑
|
||||
| relative humidity | ratio of the amount of water vapor in the air, to the maximum amount it can hold. it is usually expressed as a percentage
🗑
|
||||
| sling psychrometer | instrument to measure dew point and relative humidity
🗑
|
||||
| how are winds described? | the direction they come from
🗑
|
||||
| how do winds generally blow? | from high pressure to low pressure
🗑
