QNH and Density Altitude
This chart shows the QNH (in hPa). For those fields with known elevation density altitude (in feet) is also shown. Field elevation: 23
Wind Direction and Intensity
This chart shows the Wind intensity, gusts (both in kt) and directon (deg).
Note that wind intesity is the average speed over a 2-minute period (direction may not be reported when below 6 knot)
Note also that Gusts are indicated by rapid fluctuations in wind speed with a variation of 10 knots or more between peaks and lulls
