|
stormy |
|
freezing |

hot |
Cirrus clouds are thin, wispy high-altitude clouds composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus clouds generally occur in fair weather and point in the direction of air movement at their elevation.
These clouds grow upward and can develop into cumulonimbus or thunderstorm clouds.

A transition zone between two air masses is called:
fog |
|
boundary |
|
thunderstorm |
|
front |
An air mass is a large body of air that has similar moisture (density) and temperature characteristics. A front is a transition zone between two air masses.
When two air masses meet and neither is displaced, what kind of front is present?
occluded |
|
cold |
|
stationary |
|
warm |
When two air masses meet and neither is displaced, a stationary front is created. Stationary fronts often cause persistent cloudy wet weather.
