Climate Flashcards
(34 cards)
El Nino
characterized by low pressure and storms in the eastern pacific and high pressure and drought in the western pacific, wet winters in the southeastern and southwestern United States, relatively warm winters in Canada and the northern United States, and fewer Atlantic Ocean hurricanes.
La Nina
characterized by high pressure and drought in the eastern pacific and low pressure and storms in the western pacific, cold winters in Canada, wetter winters in the Pacific Northwest, warmer, drier winters in the southeastern and southwestern United States, and more Atlantic Ocean hurricanes
Climate
the product of weather over time. Or a combination of temperature, moisture, precipitation, and winds for a given place expressed as means which describes the climate
Air pressure decreases..
with increasing altitude. Air becomes less dense, gets colder
Dry Adiabatic Rate
In dry air, temperature changes drastically
Moist Adiabatic rate
slower decrease in temperature as altitude increases, this is due to the water in the air that acts as a buffet due to its high specific heat
Between the Hadleys
warm air is rising and cooling, clouds form, and there is precipitation due to low pressure
Between Hadley and Ferrell cells
There is high pressure as cold air is sinking, weather is being suppressed, little rain (desert areas in this cell). Tropical warm airs spread to poles.
between Polar and Ferrell cells
Hot air rising and cold air headed to equator, low pressure, clouds are produced and rain

Northern Hemisphere has _____ equinox as the equator faces ______ from the sun.
autumnal, faces
Southern Hemisphere has _____ equinox as the equator ____ the sun.
spring, faces
Northern hemisphere has _____ equinox as the equator ____ the sun.
Spring, faces
Southern Hemisphere has _____ equinox as the equator faces ____ from the sun
Autumnal, away
intertropical convergence zone (ICZ)
the region where the Tradewinds meet, located in the center of the Hadley Cells, it is a region of rising, unstable air, cloudiness, and rain
Where in the ITCZ in the summer?
On the hemisphere (Northern)
Where is the ITCZ in the autumn/spring?
close to the equator, right above it/right below it
Where is the ITCZ in the winter?
On the southern hemisphere (opposite one)
