Identify the five main factors that affect climate and explain how each affects climate.

1. Latitude 2. Closeness to large bodies of water 3. Proximity of mountain ranges 4. Elevation 5. Ocean Currents

How does latitude affect climate? As latitude ________, the average annual temperature _________. 0° Latitude 90° Temperature decreases increases

Tropical Latitudes

Tropic of Cancer The Tropic of Cancer, also referred to as the Northern tropic, is the circle of latitude on the Earth that marks the most northerly position at which the Sun may appear directly overhead at its zenith. This event occurs once per year, at the time of the June solstice, when the Northern Hemisphere is tilted toward the Sun to its maximum extent.

Tropic of Capricorn The Tropic of Capricorn, or Southern tropic, marks the most southerly latitude on the Earth at which the Sun can be directly overhead. This event occurs at the December solstice, when the southern hemisphere is tilted towards the Sun to its maximum extent.

Arctic & Antarctic Circle

60 th Parallel At this latitude the sun is visible for 18 hours, 52 minutes during the summer solstice and 5 hours, 52 minutes during the winter solstice. On 21 June, the sun is at degrees up in the sky and 6.17 degrees on 21 December

Barrow, Alaska In Barrow, the sun does not set between May 10 and August 2 each summer, and does not rise between November 18 and January 24 each winter. This is because the city is about 400 miles north of the Arctic Circle.

Barrow, Alaska The Arctic Circle marks the southern limit of the area where the sun does not set on the summer solstice or rise on the winter solstice. Continuous day or night ranges from one day at the Arctic Circle to six months at the North Pole.

How does closeness to a large body of water affect climate? Water __________ the temperature. _______ summers. _______ winters. City B is closer to a large body of water. Its temperature line is flatter (moderated). moderates Cities A & B are located at the same latitude. CoolerWarmer

The windward sides of the Adirondacks & Catskills receive a great deal more precipitation The leeward sides of the Adirondacks & Catskills receive much less precipitation

How does the Orographic Effect affect climate? Windward Side: ___________ Leeward Side: _____________ cool, moist warm, dry

Page 14 of the ESRTs We live in the troposphere. Temperature decreases with elevation.

During summer, temperature is strongly controlled by elevation -- cold at the higher reaches of the Alaska and Brooks Ranges, and warmer in the lowlands.

How does elevation affect climate? As elevation _________, the average annual temperature __________. Elevation Temperature increases decreases

How do ocean currents affect climate? Warm Currents: warmer climate Cold Currents: cooler climate
