The student will investigate and understand how weather conditions and phenomena occur and can be predicted. Key concepts include:
• weather measurements and meteorological tools
air pressure - barometer
wind speed - anemometer
rainfall - rain gauge
temperature - thermometer
- weather phenomena ~ fronts, clouds and storms
They use data to predict weather patterns.
air pressure - is due to the weight of the air and is determined by several factors including the temperature of the air

temperature - the measure of the amount of heat energy in the atmosphere

(how hot or cold)

(moving air)
Types
of Clouds
in the Sky
(the form of water that falls from the clouds, such as rain, sleet, snow and hail)
What types of weather are associated with high and low pressure masses?
Be able to illustrate and label high and low pressure air masses
and warm fronts and cold fronts.
- fluffy and white with flat bottoms
- usually indicate fair weather
- when they get larger and darker on the bottom, they produce thunderstorms
- smooth, gray clouds that cover the whole sky
(they block our direct sunlight)- light rain and drizzle are usually associated with these
- feathery clouds
- associated with fair weather
- often indicate that rain or snow will fall within several hours
- can cause lightning, thunder, hail, strong rains, strong winds, and tornadoes
