Pressure
Can be thought of as the weight of air on the surface
What is air pressure
The instrument used to measure wind speed
What is an anemometer
The jet stream is found at the boundary between the troposphere and this layer.
What is stratosphere
This is the pressure center and hemisphere if winds flow Counterclockwise Into the center
What is low pressure in the Northern Hemisphere
The instrument that measures air pressure
What is a barometer
The force that generates the wind, and determines its strength
What is the pressure gradient force
Planes can fly faster going this direction across the country due to the jet stream
What is east
Increasing moisture, increasing elevation, and increasing temperature will all do this to air pressure.
What is cause it to decrease.
The pressure associated with rising air currents, cloudy weather, and rain.
What is low pressure
Large scale winds do not flow straight, but rather in a curved path. This is the reason for that curving pattern.
What is Coriolis Force or Earth's rotation
When cooler, nutrient rich waters rise to the surface due to the removal of surface water by the prevailing winds
What is upwelling
Virginia is found in this wind belt.
What is the prevailing westerlies
Lines on a map that connect pressure
What is an isobar
This affects winds along the surface of Earth, but not winds aloft.
What is friction.
During an El Nino year, water temperatures in the Eastern Pacific will do this as upwelling is cut off.
What is rise
It is important to be able to predict El Nino events, because the changes in weather affect these two categories of public interest.
What is human health, and economy.
A low pressure center is known as this
What is a cyclone
The uneven pressure that causes wind, is caused by the differences in this across Earth's surface.
What is heat capacity or heating rates
These are the two directions that are most associated with the jet stream in North America
What is NW and SW
The prevailing winds that blow from the horse latitudes to the doldrums.
What are the trade winds
