Sunshine for any point is assessed using the model representation of cloud layers to decide how much direct solar (shortwave) radiation reaches the Earth's surface...
Interval/period: N/A
Predicting near surface visibility is dependent on predicting the correct dynamic and thermodynamic conditions in the boundary layer which can be highly variable. Fog is an extremely important weather hazard...
Interval/period: N/A
The movement or transfer of vorticity helps in the assessment of vertical motion of air (ascent) in the troposphere. Where a local vorticity maximum approaches an area there is a tendency for air to rise and where a local vorticity maximum moves ...
Interval/period: N/A
Vorticity is the tendency of an air particle to rotate or circulate around a particular point. Relative Vorticity is a measure about a vertical axis of the local rotation or spin of the air relative...
Interval/period: N/A
The air flow is not the same at all levels and can be very different in strength and direction when associated with vigorous weather systems...
Interval/period: N/A
Uncoloured areas (relative humidity < 65%) are likely to be free of cloud. Coloured areas (relative humidity > 65%) show where moisture is likely to be available for cloud development...
