From autumn to spring in December 1806

December 2015 is most definitely an odd one. With its weather statistics and Natural World tales, it is certainly becoming one for the history books. Although, it is worth noting that we have been here before, as this example from 1806 shows, courtesy of the wonderful Wanstead Meteo blog. Of course, my current mean Temperatures of 5.4c above average could and perhaps should still be viewed as rather concerning.

When I was writing up my winter forecast I came across an analogue that was very similar to what seems to be unfolding this December.

Luke Howard, in his first volume of The Climate of London, describes a very warm December that followed on from a warm November that fooled flora and fauna into thinking spring had begun early.

Howard’s statistics are very high: a November mean of 9.5C while December was 9.3C. CET that November was 2.3C above average while December was 3.3C above average. A slightly wetter than average was followed by a very wet December – over 250% the monthly average caused the River Lea to burst its banks in several places

“The catkins of the filberts expanded prematurely. On December 25th a hedge sparrow’s nest was taken at Doveridge, Derbyshire, with four eggs and…

The images you may well have missed

Knowing that not everyone is on Facebook, here is the latest naturestimeline imagery in all its glory or not, as the case may be.

January and February datasets

As promised, how is the phenology looking against a backdrop of a very wet but reasonably mild Winter. One notable thing for me were the number of Thunder days, four in total, all of which occurred before the 16th January. This is quite exceptional under any circumstances and as a consequence there is a notable shift towards earlier day numbers.

Now onto the flowering plant and shrub species. The flowering plant species witnessed for the first time in Winter were Woodland Snowdrop, Winter Aconite, Daffodil (cultivated type), Primrose and Lesser Celandine. The flowering shrub species were the Hazel with its catkins and the Blackthorn in blossom.

Several of the above events are generally regarded as not suitable for accurate phenological tracking by certain well-known naturalists, can you guess which ones?

Two insect species were seen on the wing for the first time before the end of February and these were the first Bumblebee, presumably of the genus bombus terrestris as well as Brimstone butterfly. Below are the respective day numbers and rolling averages over a succession of years for those seasonal treats.

There were some other bird related sightings occurring for the first time this year, some of which will be apparent when looking at MY NATURAL EVENTS CALENDAR. I hope to blog about these over at ukbirdingtimeline soon, in the meanwhile, I will leave you to ponder any determinable trends in the data alongside some images of the above phenomena.
