1-16 day weather forecast Europe (GFS)


700 hPa height + vertical motion




Source: Wetterzentrale



White lines + values = height contours at 700 hPa, each 4 gpdam.
Colored zones = vertical motion 700 hPa each 2 hPa on which:
positive values = downwards motion, negative values = upwards motion

Useful for: negative values indicate frontal activity or instability, positive values indicate subsidence.
For the negatives values: long elliptic zones indicate frontal zones, more individual cells usually indicate zones of more structured instability like troughs, region of showers. Structured negative fields near mountains are a strong indication for active orographical precipitation.
