Weather Part A

Which best explains the effect a tornado has on normal wind speed and direction?

• a tornado does not affect wind speed or direction
• a tornado increases wind speed and may change its direction
•  a tornado decreases wind speed and may change its direction
• a tornado causes wind direction to reverse and may change its speed

Which is generally considered the least important in determining the local weather conditions of an area?

• landforms
• wind speed
• precipitation
• temperature

Which conditions will result in high wind?

• large differences in air pressure
• heavy rains over several days
• increase in evaporation rates
• presence of cirrus clous

Which will be the effect of a warm front moving into the area?

• light precipitation will begin as the front arrives and remain after the front is gone
• light precipitation will begin as the front arrives and clear after the front is gone
• Skies will clear as clouds are moved by the front and grow cloudy after the front is gone
• skies will clear as clouds are moved by the front and remain clear after the front is gone

How would weather conditions in an area change if a high pressure system replaced a low pressure system?

• The area would become stormy and rainy
• The area would become more humid and warmer
• The area would become cooler with less humidity
• The area would become warmer with strong winds

What type of weather is usually found in low pressure areas?

• hot and dry
• wet and stormy
• cold and snowy
• sunny and humid

Based on the information in the table, in which city will it most likely rain?

• City W
• City X
• City Y
• City Z

Which type of air pressure causes a storm to form on a spring day?

• low pressure, causing air to rise, cool, and form water droplets
• high pressure, causing air to rise, cool, and form water droplets
• low pressure, causing air to sink and bring water droplets to the ground
• high pressure, causing air to sink and bring water droplets to the ground

How does the ocean affect the weather along the coast of North Carolina?

• It causes less wind along the coastal areas than farther inland
• It causes less severe weather along the coastal areas than farther inland
• It causes less change in temperature along the coastal area than farther inland
• It causes more frequent changes in humidity along the coastal areas than farther inland

What is most associated with a thunderstorm?

• low air pressure
• high air pressure
• winds blowing from the West
• winds blowing from the East
