Topic 4 The Atmosphere
The present condition of the atmosphere.
the study of Earth's atmosphere and weather
any line that connects equal values on a map. There are three main types of isolines: isotherms, isobars and contour lines.
a line that connects equal air pressure values on a map
a line that connects equal temperature values on a map
the weight of a column of air. It is commonly called air pressure and/or barometric pressure
the process of gas turning to liquid. the most important example is water vapor turning to liquid water droplets to form a cloud
a measure of how much water vapor is in the air at a certain temperature compared to how much it could hold.
100% Relative Humidity
Air is holding all the water vapor it can and the air is said to be "saturated" or its full.
an instrument that measures wet bulb and dry bulb temperatures and can lead to figuring out dew point temperature and relative humidity.
the change in air pressure between two locations over a certain distance
Due to Earth's rotation, winds and ocean currents are "curved" or "deflected" to the right of their path in the Northern hemisphere.
the movement of a fluid (gas or liquid) caused by differences in density. Less dense fluids will rise while more dense fluids will sink.
a surface that water vapor can condense onto.
the amount of heat energy need to raise 1 gram of a substance 1 degree Celsius
