Weather Review

Why do clouds usually form at the leading edge of a cold air mass?

• Cold air contains more dust than warm air does
• Cold air flows over warm air, causing the warm air to descend & cool
• Cold air contains more water vapor than warm air does
• Cold air flows under warm air, causing the warm air to rise & cool

The atmospheric pressure at the center of the low would most likely be

• 994 mb
• 988 mb
• 990 mb
• 997 mb

Which statement best describe the relationship between relative humidity & air temperature?

(WATER CONTENT STAYS THE SAME)

• RH decreases as air temperature decreases
• RH remains the same as air temperature decreases
• RH increases as air temperature increases
• RH decreases as air temperature increases

According to the ESRT, when the dry-bulb temperature reading is 10^oC & the wet-bulb temperature is 2^oC, the dewpoint temperature of the air is approximately

• 10^oC

• 2^oC
• -8^oC
• -14^oC

When molecules of water evaporate into the air & replace the heavier molecules of oxygen and nitrogen, the density of the air generally

• Increases
• Decreases
• Remains the sam

The rate of evaporation of water can be increased by

• Decreasing the circulation of the air
• Increasing the temperature of the air
• Decreasing the temperature of the water
• Increasing the amount of moisture in the air

A temperature of 104^oF is equal to a temperature of

• 136^oC
• 40^oC
• 104^oC
• 72^oC

If low-pressure system follow the path of most weather systems in the United States, in which direction will they move?

• Southwest
• Northwest
• Northeast
• Southwest

An air mass from the Gulf of Mexico, moving north into NYS, has a high relative humidity.  What other characteristics will it probably have?

• cool temperatures & high pressure
• warm temperatures & low pressure
• warm temperatures & high pressure
• cool temperatures & low pressure
