Factors that Affect Weather
Definitions
Precipitation
Labs, etc.
100
very windy and cold conditions; falling snow and reduced visibility
What is a blizzard?
100
high speed winds in the upper troposphere caused by pressure differences between the warm and cold regions of the world.
What are jet streams?
100
measure of the amount of water vapor in the atmosphere
What is humidity?
100
layer of the atmosphere that we look at the most when forecasting weather
What is the troposphere?
100
general direction that all weather systems move in Canada
What is toward the east (southeast)
200
average rainfall for an area drops below normal for a long period of time
What is drought?
200
have low heat capacity, so it heats up and cools more quickly. This causes cloud formation and local weather effects
What are land masses?
200
local convection current set up during the day
What is a thermal?
200
3 processes that bring all moisture back to the atmosphere
What are evaporation, sublimation, and transpiration?
200
three changes you can make to increase the rate of evaporation of water
What are (so many)...
300
change in wind direction and increase wind speed with increasing height; horizontal spinning
What is a tornado?
300
large scale winds help maintian Earth's energy balancy by moving energy from the hot equator toward the poles
What are prevailing winds?
300
warm, dry air brought toward the east by air moving over mountains
What are Chinook winds?
300
type of precipitation that is like rain, but droplets are much smaller
What is drizzle?
300
this happens when a warm front catches up to a cold front
What is precipitation?
400
elevated water levels above the banks of a water system or immersed land due to intense rainfall
What is a flood?
400
help maintain the energy balance on Earth. Absorb infrared radiation. Help with the water cycle,
What is Cloud Cover?
400
perceived change in direction of a moving object on a rotating system
What is the Coriolis Effect?
400
when ice crystals move through warm air patch in the atmosphere, then refreezes again before hitting the ground
What is sleet?
400
three types of weather forecasting technologies
What are satellites, balloons, and ground based technology?
500
high surface water temperature and evaporation occurs, which feeds convection currents.
What is a hurricane?
500
this takes longer to heat up and cool down; majority of Earth's surface is covered in this.
What is the Hydrosphere?
500
blanket of air and moisture that surrounds the earth
What is the atmosphere?
500
once moisture is evaporated up into the clouds, it undergoes this process before forming different types of precipitation
What is condensation?
500
how is fog different than other clouds?
What is the location (close to the ground)?
