1
Q

El Nino

A

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.

A

with increasing altitude. Air becomes less dense, gets colder

Q

Moist Adiabatic rate

A

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

Q

Between the Hadleys

A

warm air is rising and cooling, clouds form, and there is precipitation due to low pressure

Q

Between Hadley and Ferrell cells

A

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.

16
Q

When does Alaska has 24hrs of darkness?

A

In winter

17
Q

Northern Hemisphere has _____ equinox as the equator faces ______ from the sun.

A

autumnal, faces

18
Q

Southern Hemisphere has _____ equinox as the equator ____ the sun.

A

spring, faces

19
Q

Northern hemisphere has _____ equinox as the equator ____ the sun.

A

Spring, faces

20
Q

Southern Hemisphere has _____ equinox as the equator faces ____ from the sun

A

Autumnal, away

21
Q

intertropical convergence zone (ICZ)

A

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

22
Q

Where in the ITCZ in the summer?

A

On the hemisphere (Northern)

23
Q

Where is the ITCZ in the autumn/spring?

A

close to the equator, right above it/right below it

24
Q

Where is the ITCZ in the winter?

A

On the southern hemisphere (opposite one)

25
Q

The Coriolis Force

A

the rotation of the Earth itself causes objects that are moving (air and water) to be deflected at higher latitudes

26
Q

Objects in the Northern hemisphere are deflected in a ______ direction.

A

clockwise

27
Q

Objects in the northern hemisphere are deflected in a _____ direction

A

Counterclockwise

28
Q

Benjamin Franklin

A

studied currents while he was the first US postmaster. (First to map a current, the gulf stream)

29
Q

Carl Ludwig Willdenow

A

He is considered one of the founders of phytogeography, the student of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt one of the earliest and best known phytogeographers. He pointed out that similar climates support similar vegetation.

30
Q

Humboldt

A

Friedrich Heinrich Alexander von Humboldt described vegetation in terms of outward appearance, correlated vegetation types with environmental characteristics and coined the term “plant association”

31
Q

Formation of a rain shadow

A

A rain shadow forms when moist winds head towards a set of mountains and get forced upwards by them. The air gets cooled down and cool air can’t hold as much water, so the water is lost as precipitation. The water never makes it over the mountain; the other side of the mountain has arid, dry climate

32
Q

Microclimate in Northwestern

A

North facing mountain is going to be more shaded than the south facing one therefore the plants on the north mountain are going to retain more water because the sun is not beating down on it. There is more lush on the north and the south is chaparral and arid. Ex: snow on north facing mountain.

34
Q

Windbreak

A

Vegetation deflects wind and on the other side there is a “quiet zone” where animals and plants can thrive. The quiet zone experiences higher temperatures and a higher relative humidity. Does NOT create a microclimate, just reduces windspeed
