- The state of the atmosphere at a specific time and place.
- Temperature is defined as the measure of the average speed of atoms and molecules. The higher the temperature the faster they move.
- Is defined as the force acting on a surface from another mass per unit area.
- Low Pressure
An area of atmospheric pressure within the Earth's atmosphere that is below average. If this system is on the Earth's surface and contains circular wind flow and enclosed isobars it is called a cyclone.
A general term used to describe the amount of water vapor found in the atmosphere.
- High Pressure
An area of atmospheric pressure within the Earth's atmosphere that is above average. If this system is on the Earth's surface and contains circular wind flow and enclosed isobars it is called an anticyclone.
The steepness of a slope as measured in degrees, percentage, or as a distance ratio (rise/run).
A state of matter where molecules are free to move in any direction they like. The state of matter where the substance completely fills any container that it occupies.
Is defined as the capacity for doing work. Energy can exist the following forms: radiation; kinetic energy; potential energy; chemical energy; atomic energy; electromagnetic energy; electrical energy; and heat energy.
Convection involves the transfer of heat energy by means of vertical mass motions through a medium.
General pattern of weather conditions for a region over a long period time (at least 30 years).
The atmosphere is the vast gaseous envelope of air that surrounds the Earth. Its boundaries are not easily defined. The atmosphere contains a complex system of gases and suspended particles that behave in many ways like fluids. Many of its constituents are derived from the Earth by way of chemical and biochemical reactions.
Vertical distance above sea-level.
Advection involves the transfer of heat energy by means of horizontal mass motions through a medium.
- Air moving horizontally and/or vertically.
