Front definition Stationary front Occluded front |
Front is a boundary layer between two types of airmass Stationary front occurs when the forces of two airmasses are relatively equal, the front that separates them remains stationary and influences the local weather for days Occluded front occurs when a fast-moving cold front catches up with a slow-moving warm front. |
|
|
Wind shift |
Wind shifts continually occur within a front. |
|
|
Isobar |
Isobars are lines to depict lines of equal pressure. Closely spaced isobars mean a steep pressure gradient and strong winds Widely spaced isobars mean a shallow pressure gradient and light winds |
|
|

|
Freezing level |
Freezing level is the lowest altitude in the atmosphere over a given location at which the air temperature reaches 0 |

|
Anti-Ice De-Ice |
Anti-Icing prevents the formation of ice De-icing remove the ice after it is formed. |
|
|
Dew point |
Dew point is the temperature at which the air can hold no more moisture. When the temperature is reduced to the dew point, the air is completely saturated and moisture begins to condense in the form of fog, dew, frost, clouds, rain or snow. |
