Monthly trend charts added to weather site

For anyone following the Monifieth weather station, I've added a couple of new pages showing the trends in temperature and rainfall for each calendar month. The first full month of data was recorded in July 2003 so I now have more than 7 complete years of data, which I thought was enough for a trend graph to be interesting, if not scientifically relevant (although many of the arguments in the battles between the climate change die-hards and the skeptics seem to revolve around data on a shorter time scale than that).

Have a look at the station's archive page, then select either of the "monthly trends" links in the Plots box near the top of the page.

Although it's difficult to read much into graphs over such a short time scale, it does seem that there is a pronounced trend towards colder winters and a mild trend towards colder summers over the past 4 years or so. Spring and autumn temperatures don't seem to show much of a trend either way. The averaged temperature values for entire years (visible at the bottom of the page) show a slight cooling trend over the past 4 years. Certainly no evidence of global warming in my back garden anyway.

Rainfall doesn't seem to show much of a trend, with wet and dry months occurring at any time of year. Viewed at a yearly level, the trend over the past 4 years is for increasingly wetter years, although 2004 was still quite rainy.
