Risk of precipitation (≥1.0 mm)
The risk of precipitation is the probability that more than ≥ 1.0 mm precipitation will occur.
Risk of precipitation (≥0.1 mm)
The risk of precipitation is the probability that more than ≥ 0.1 mm precipitation will occur.
Thickness & barometic pressure
Thickness is the height of the air layer until a constant pressure is reached. The higher this layer is, the more the air in the layer has expanded.
Wind 700hPa is the prevailing wind blowing in an altitude where air pressure is 700hPa. This altitude usually occurs at around 3 Km above sea level.
