4. Climate, Wind and Ocean Currents

5. Climate It is the long-term weather of that area (at least 30 years).
Two of the most important factors determining an area's climate are air temperature and precipitation.
World biomes are controlled by climate.

6. Factors that affect Temperature
The temperature of a climate are determined by 3 natural factors:
1. latitude: a measure of the distance north and south of the equator
2. elevation: distance above sea level
3. ocean currents: a “river” of water that flows in a definite path in the ocean.

7. Factors that affect Precipitation
Two natural factors affect precipitation at a particular location:
1. Prevailing winds: (which will be mentioned later)
2. Mountain ranges:
Acts as a barrier against prevailing winds
Will determine the amount of precipitation an area will get

8. side of mountain facing wind:
Windward side:
windward
side of mountain facing wind:
receives moisture with lots of precipitation because air comes from ocean.

9. Leeward side
Leeward
side away from the wind
receives very little precipitation because air comes from land

10. Winds
caused by differences in air pressure due to unequal heating of the atmosphere
formed by the movement of air from one place to another.
Two types of winds occur in the atmosphere
Local
Global

11. Local Winds Blow from any direction and usually cover short distances.
Two types:
Sea breeze: a flow of air from the sea to the land
Cool air rises, warmer air moves in to take its place
Occurs during the day
Land breeze: a flow of air from land to sea
Warm air rises, cooler air moves in to take its place
Occurs at night

12. Stronger global winds:
Prevailing westerlies:
40° to 60° latitude in the north and south hemisphere;
strong winds
Trade winds:
30° north and south of the equator;
warm air rising from the equator cools and begins to sink; sky is clear

13. Weaker global winds: Doldrums: Polar easterlies:
50° to 90° latitude in both hemispheres;
cold weak winds
Doldrums:
5° to 0° latitude in the north and south hemisphere very near the equator,
an area with no wind or light variable winds

14. Coriolis Effect is the curving of moving
objects from a straight path due to the Earth’s rotation.
this causes all the global winds to blow either to the right or the left as they blow
In the North, winds blow to the right.
In the South, the blow is to the left.

15. Ocean Currents
Are influenced by weather, Earth’s rotation, and the position of the continents.
Two types of currents that occur in the ocean:
Surface
deep

16. Surface Currents
Are stream-like movements that occur at or near the surface of the ocean
These waters make up about 10% of all the water in the ocean.
These waters are the upper 400 meters of the ocean.

17. Deep Currents
Are stream-like movements of ocean water far below the surface.
These waters make up the other 90% of the ocean
These deep waters sink into the deep ocean basins at high latitudes where the temperatures are cold enough to cause the density to increase.
Factors that combine to affect the density are:
temperature
salinity

18. How would the climate in Texas change if a cold-water surface current did not run along Texas’ coast?
The climate would remain the same.
The climate would become warmer.
The climate would become cooler.
The climate in Texas is not affected by surface currents.
