Temperature is a measure of the warmth or coldness of an object or substance with reference to a
standard value. It can be measured in Kelvin (K), Fahrenheit (F), or Celsius (C).
Air in motion relative to the surface of the earth. Wind develops from pressure differences in the
air. An area of high pressure and low pressure oppose each other and set up a pressure gradient force that moves
from high to low pressure. This force creates a wind as air is pushed in the according direction. The stronger
the pressure difference, the stronger the force, and the stronger the resultant wind. Wind is described as the
prevailing direction of which the wind is blowing as a speed in units of miles per hour or knots.
The force exerted by the weight of the atmosphere and gravity. Different units: atmospheres (atm),
millibars (mb), pascals (Pa), inches of mercury (in), pounds per square inch (PSI), etc. Meteorologists most often use mb.
The rain measured in a specified period of time (e.g. daily, monthly, yearly).
That part of the electromagnetic spectrum between 5 - 400nm.
A measure of the severity of solar proton events as depicted in the NOAA Space Weather Scales.
