What is weather
physical change in the lower atmosphere over a short period of time (hours to days)
-
What is climate
pattern of change in the atmosphere over a longer period of time (at least 3 decade to thousands of years)
-
what 3 major factors determine how air circulation in the lower atmosphere
- -uneven heating of the earth surface by the sun
- -rotation of the earth on its axis
- -properties of air, water, and land
-
ocean effect regional climates
-
Warm Front
Boundary between an advancing warm air mass and the cooler one it is replacing
-
Cold Front
leading edge of an advancing mass of cold air
-
what type of climate is associated with low pressure
Cloudy and Stormy weather
-
what type of climate is associated with high pressure
clear skies and sunny
-
what is upwelling
an upward movement of ocean water
-
Define Tornato
Swirling, funnel-shaped clouds that form over land
-
what is the difference between an hurricanes and typhoons
Hurricanes form in the atlantic ocean while typhoons for in the pacific ocean
-
What are some ecological and economic benefits of tropical cyclones
- -Tropical cyclones can flush bays and marshes which reduce brown tides,
- -Increase growth of sea grass, and
- -Increase production of commercially important species of shellfish and fish
-
Four main greenhouse gases
Water vapor, Carbon Dioxide, Methane, and Nitrous oxide.
-
Global warming
Warming of the earth's lower atmosphere because of increases in the concentrations of 1 or more greenhouse gases. can result in climate changes
-
Rain shadow effect
Low precipitation on the leeward side of the mountain when prevailing winds flow up and over a high mountain or range of high mountains, creating semiarid and arid conditions on the leeward side of a high mountain
-
What are Biomes
Large terrestrial regions each characterized by certain types of climate and dominant pant life.
-
Biomes in the United States
Coastal Chaparral and Scrub, Coniferous forest, Desert, Prairie grassland, and Deciduous forest
-
how latitude affect Biomes and how does elevation affect Biomes
Latitude decreases and elevation increases (tropical forest> Deciduous> Coniferous forest > Tundra > polar Ice/snow
