- What are Trade Winds?
- Describe the Equatorial Low Pressure.
- Describe land-sea breezes.
- What is the rule for naming winds?
- a The wind direction is always reported as the direction from which the wind is blowing. Winds which blow from the west, for example, are westerlies. They blow towards the east. Winds which blow from the south are called southerlies. They blow towards the north.
- b Equal wind speed.
- c Trade Winds blow out of the equator side of the anticyclones. In the Northern Hemisphere, they are the Northeasterly Trade Winds. They are the most persistent winds in the world, blowing in the same direction about 80% of the time.
Land-sea breezes are driven by the thermal inertia of water. When land and sea receive the same amount of insolation, the land heats up faster than the water. This temperature gradient causes winds to blow. At night, radiational cooling cools the land faster than the water so that the temperature gradient makes a wind blow from land to sea. These breezes also occur for large bodies of water, such as the Great Lakes.
- e The Equatorial Low Pressure area occurs along the Intertropical Convergence Zone (ITCZ) and is the area where the Trade Winds and doldrums occur.
5 Multiple choice questions
- Tertiary circulation is the movement of local high and low pressure cells, and parcels of air will cause local weather patterns, such as the weather patterns of a coastal city that is influenced by the body of water nearby.
- Low pressure cells tend to ascend and converge.
- An isoline connecting all points of highest mean temperature.
The Coriolis Effect deflects winds fro ma straight line in relation to the Earth's rotating surface. Earth's rotation adds the Coriolis Effects and a "twist" to air movements. In the Northern Hemisphere, winds are deflected to the right, or the east. In the Southern Hemisphere, winds are deflected to the left, or the west.
- The Subtropical High Pressure area consists of Westerlies, the Bermuda High, the Azores High, and the Pacific High.
5 True/False questions
What are the four major pressure areas on Earth? →
The four major pressure areas on Earth are the Equatorial Low (warm, wet 10 degrees N/S), Polar High (cold, dry 90 N/S), Subtropical High (hot, dry 20-35 N/S), and the Subpolar Low (cool, wet 60 N/S).
Isoheight or contour line is what? → Equal elevation.
What does primary circulation in the atmosphere entail? → Tertiary circulation is the movement of local high and low pressure cells, and parcels of air will cause local weather patterns, such as the weather patterns of a coastal city that is influenced by the body of water nearby.
What are the rules for isopleths? → Isopleths must be continuous and cannot intersect other isopleths. All values above the isopleth should be on one side of the line and all values below an isopleth should be on the other side of the isopleth. The position of the isopleth should be interpolated in between points of known data. They should choose a contour interval and start at an area of high or low values.
Isotherms are equal to what? → An isoline connecting all points of highest mean temperature.
