Science 2015: Weather And Climate Flashcards
Climate
Yeah after year conditions of temp, rain, winds and clouds in an area
Climate is determined by
Temperatures and rain
Things that influence temp
Latitude, altitude, distance from large bodies of water and ocean currents
Suns rays hit
Mainly at the equator
Latitude
Distance from the equator (3 zones)
Continental climates
Land
Marine climates
Water
Marine currents influenced by
Ocean currents
What effects rain
Prevailing winds and presence of mountains
Windward
Side of the mountain where oncoming wind hits
Leeward
Side opposite of the side that rain hits
Seasons are caused by
Tilt of the earths axis as earth travels around the sun
Rising into the air..
Air gets colder and less dense
Four layers of the atmosphere are classified by
Changes in temperature
Layers of the atmosphere
Troposphere
Stratosphere
Mesosphere
Thermosphere
Lowest layer of atmosphere
Troposphere (we live in it)
What is a shooting star
Trail of hot glowing gases a burning meteoroid leaves behind
Aurora Borealis
Northern lights that takes place in the ionosphere
Why is the mesosphere the coldest
The outer layer is not protected by the heat provided by the ozone layer
Air down to the surface causes
High pressure
Horizontal movement of air across earths surface
Wind
Air masses
Body of air with similar characteristics throughout
Air mass is classified by
Humidity and temp
Maritime
Humid (wet) air masses
Continental
Drier air masses that form over land
Polar
Cold air masses out of the North
Tropical
Warmer air masses from the south
Weather front
Area where two air masses meet and they don’t mix. Boundary between two or more air masses
Cold front
Fast moving cold air that runs into a slow moving warmer air mass
Warm front
Warm air mass collides with a slow moving cold air mass
Stationary front
Cold air mass and warm air mass meet but neither are being moved
Occluded front
A warm air mass is caught between two cooler air masses and is lifted above them
Air pressure depends on
Number of air molecules in a given space and how fast they’re moving
Northern hemisphere air travels
Clockwise
Southern Hemisphere air travels
Counterclockwise
Middle latitudes
Where polar and tropical winds meet and create storms
Cirrus
Thin and wispy
Cumulus
Puffy and billowy
Stratus
Flat and sheet like, covers the whole sky
Cirro-
High clouds about 20,000 feet
Alto-
Middle clouds
Nimbo- -nimbus
Clouds that bring rain
Weather
Day to day events referring to condition of atmosphere at a certain time and place
