Weather Events

Parameter	Description
Precipitation	Broad precipitation bands (5-50 km wide) are found within, and ahead of, the surface front. Maximum precipitation occurs close to the occlusion point (in contrast to occlusion: cold conveyor belt type). At the rear part of the cloud spiral, showers and thunder or even hail can exist.
Temperature	Seasonal dependence: rising temperatures in wintertime, cool conditions in the summer.
Wind (incl. gusts)	Moderate to strong winds. The most intense wind occurs on the outer edge of the cloud spiral.
Other relevant information	Generally, occlusions are connected with multi-level clouds. Therefore the weather activities are highly variable.

Note: for a larger SYNOP image click this link.

The cloud band of the WCB occlusion shows wide spread precipitation, Cb and shower reports from synoptic measurements. The probability of moderate rain from the NWCSAF analysis is widespread - up to 45 % (which can, according to the NWCSAF analyses evaluations, already be connected with precipitation). Smaller areas and spots with higher analysis probabilities are connected to corresponding Cb and even to thunderstorm reports.
