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...

Interval/period: N/A
The 850 hPa level is usually just above the boundary layer and at this level the day-night variation in temperature is generally negligible...
Interval/period: N/A
Wind speed at 200 hPa highlights the jet stream (areas of strong winds in the upper troposphere) which can help identify movement and development of depressions...
Interval/period: N/A
Wind speeds near the surface are roughly proportional to the distance between isobars so closely packed isobars mean strong surface winds...
