Components of Weather
Is qualitatively, the coolness or warmth of something; quantitatively, the average kinetic energy of the particles of a substance
What is Temperature?
is a mechanism of energy transfer in which atoms or molecules give off energy in the form of electromagnetic waves
What is Radiation?
the transfer of thermal energy between two substances that are in direct physical contact
What is conduction?
An air mass cools over an ocean or cold region of land which will form a _________
What is a high pressure system?
Occur between the equator and 30o north latitude or 30o south lattitude
What is trade winds?
any liquid or solid form of water that falls to Earth from the atmosphere, including rain, snow and hail
What is Precipitation?
any substance that can absorb and train energy without changing state
What is a heat sink?
transfer of thermal energy by the vertical movement of heated material from one place to another
What is Convection?
Air masses that travel over warm land or oceans may develop into ____
What is low pressure systems?
Occurs between 30o and 60o north/south latitude.
What is prevailing westerlies?
the force of the atmosphere on the surface below it
What is Atmospheric Pressure?
All the water on or near the Earth's surface
Hydrosphere
A state change from gas to liquid
What is condensation?
the change in the direction of moving air, water, or any objects on Earth's surface due to its rotation
What is Coriolis effect?
Occurs between 60o north/south latitude and the North or South Poles
What is Polar easterlies?
The wind is described in
What is speed and direction?
the proportion of the incident light or radiation that is reflection by a surface
What is Albedo?
A state change from liquid to gas?
What is evaporation?
Warm and cold air meet, and neither air mass has the force to move the other forms a ___.
What is a stationary front?
a large temperature gradient in upper-level air combined with the Coriolis effect results in strong westerly winds called ____.
What are jet streams?
The amount of water vapour in the air
What is Humidity?
very large mass of air with nearly uniform properties of temperature, humidity, and pressure
What is air mass?
The percentage of radiation that reaches and is absorbed by Earth's surface (land and water)
What is 50%?
What is an occluded front?
a zone that develops as a result of the meeting of two air masses with different charatceristics
What is a front?
