Station 24: Weymouth

Weymouth_FigA.png

Figure 'a': Monthly mean surface temperature for the entire duration of the record at the station which are derived from simple averaging of all the monthly data.

Weymouth_FigB.png

Figure 'b': Monthly climatic average with the first standard deviation. The standard deviation has been derived from the difference in the monthly average from the long-term mean (1971 - 2000).

Weymouth_FigC.png

Figure 'c': Yearly anomaly from the base period. Where the average base period temperature (1971 - 2000) has been subtracted from the average annual temperature. The standard deviation of the annually averaged temperature of the entire record is also shown. A trend line derived from a linear least squares analysis has been added to indicate the extent to which annual changes are linear.
