Monthly patterns

Posted: 18 Oct 2010 05:47 AM

Continuing along looking at the diurnal cycle of temperatures, the featured graph presents the monthly average for six months out of the year. The weakest signal is shown in January and the strongest in September. It is interesting to contrast the patterns as September has the most rapid warming, but also the most rapid cooling. This is a result of still having significant sunshine, but also dry air allowing the rapid changes. It is curious to note how similiar July and May are. This analysis is based on minute interval data dating back to only 2000.
