A stationary front is a front in which

• There is no difference in temperature between the two air masses

• There is no wind on both sides of the front

• There are never frontal clouds

• There is no horizontal motion perpendicular to the front

A small, supercooled cloud droplet that collides with an airfoil will most likely

• travel back over the wing, creating rime ice

• freeze immediately and create rime ice

• travel back over the wing , creating clear ice

• freeze immediately and create clear ice

A parcel of moist but not saturated air rises due to adiabatic effects. Which of the following changes?

• Relative humidity

• Specific humidity

• Mixing Ratio

• Absolute Humidity

Land cools faster than water at night as does the corresponding air. In this situation, the warmer air rises above the water and is replaced by the colder, denser air coming from the surface , producing an offshore wind called

• Surface Breeze

• Shore Breeze

• Land Breeze

• Sea Breeze
