What are High Clouds?

100

The state of water droplets in a liquid form below zero degrees Celsius.

What is supercooled?

100

Clouds with their bases at or very near the ground.

What is fog?

100

The diameter of a Cloud Droplet.

What is less than 20 micrometers?

100

Meteorology term that means drops of water that fall from a cloud and have a diameter of at least .5mm.

What is rain?

200

Where the base of clouds of vertical development forms.

What is the LCL (Lifting Condensation Level)?

200

One of the three basic cloud forms is a sheet or layer that covers much or all of the sky.

What is stratus?

200

Fog created over a lake...What process leads to the formation of fog over a lake?

What is evaporative cooling?

200

The temperature at which pure water suspended in air freezes.

What is -40 degrees Celsius?

200

Formed at very low temperatures and comprises individual six-sided ice crystals.

What is snow?

300

Clouds known for producing rain showers and thunderstorms.

What is a cumulonimbus?

300

One of the three basic cloud forms and high cloud types, thin, delicate, ice-crystal clouds often appear as veil-like patches or thin, wispy fibers.

What is cirrus?

300

The process involves the movement of air over a cold surface.

What is radiation cooling?

300

When colliding, raindrops stick together.

What is Coalescence?

300

Where hail is produced.

What is Cumulonimbus clouds?

400

The family at which Nimbostratus clouds usually exist.

What are low clouds?

400

A theory of raindrop formation in warm clouds.

What is the collision-coalescence process?

400

The condition where an air mass contains all the water it can.

What is saturation?

400

The temperature at which snowflakes usually melt before reaching the ground.

The temperature at which pure water suspended in air freezes.

What is 4 degrees Celsius?

What is -40 degrees Celsius?


400

What is the key concept that facilitates the Bergeron Process?

What is: "it is easier" for water vapor to deposit (deposition) directly into ice crystals than into water droplets?

500

The three basic types of clouds.

What is cirrus, cumulus, and stratus?

500

A theory that relates precipitation formation to supercooled clouds, freezing nuclei, and the different saturation levels of ice and liquid water.

What is Bergeron Process?

500

The process that leads to most types of fog.
