• False

The difference between the mixing ratio equation and the specific humidity equation is that -

• only one includes "mass of water vapor" in the numerator

• only one includes "mass of dry air" in the denominator

• only one uses dewpoint temperature in the numerator

• only one includes "mass of water vapor" in the denominator.

True or False: Farmers use misting to protect crops during mild freezing conditions. They should turn on the misters when the air temperature is 32°F.

• True

• False

True or False: Temperatures don't drop below the dewpoint temperature, because at saturation latent heat of condensation is released into the air.

• True

• False

Which statement about frost is FALSE?

• The main difference in surface conditions between frost and dew is that, for the former, the dewpoint is < 32 deg Fahrenheit

• Snow plays a role in frost formation

• Most frost forms by deposition.

• Thicker frost occurs for air temperatures around 32 deg Fahrenheit than for 28 deg Fahrenheit

One of the following statements about contouring is not true. Which statement is FALSE?

• One interpolates between given values to correctly place an isopleth

• Lines should be labeled on each end, and in the middle if it's a long line

• Contour lines never cross each other, and the final product should be smooth lines

• Contour lines never branch or fork, but extrapolation for data void regions is permissible

• A good strategy is to find local maximums and minimums first, and start drawing around one of these.

True or False: In a cloud composed of water droplets and ice crystals, the saturation vapor pressure is less over the droplets than over the ice.

• True

• False

• Warms

• Cools
