December Weather Patterns

Image
Do you remember the weather last December? Some of it wasn't pretty, such as Storm Deirdre.  In case you have forgotten, the Met Office's report states the following impact: Freezing rain caused treacherous conditions and multiple traffic accidents, particularly on the M74 and across southern Scotland, and the A66 across the North Pennines was closed. There were further traffic incidents across parts of England and Wales, reports of fallen trees and several hundred homes without power across parts of Wales and Scotland. Planes had to abort landings at Manchester Airport due to strong crosswinds. And here are some contemporary reports: https://www.theguardian.com/uk-news/2018/dec/15/storm-deirdre-batters-britain-snow-freezing-rain https://www.bbc.co.uk/news/uk-scotland-46574942 https://www.theguardian.com/uk-news/2018/dec/16/storm-deirdre-set-to-ease-after-snow-and-gales-wreak-havoc In short, not a great few days to be out and about. Was this a one off or more typical...

Here Comes the Rain - Part 2

It is official. Britain has had the wettest summer since 1912 according to the Meteorological Office . This follows one of the wettest springs on record. Is this evidence of climate change or simply natural variation in the weather? To try answering this question, data from a weather station near Glasgow has been analysed . The first part of this article presented annual rainfall records and concluded that there has been only a slight increase in annual rainfall over the past decade compared with a baseline of 1961 to 1990 but that there had been a marked increase in variability. Also of interest is whether rainfall patterns have changed throughout the year, from month to month and between the seasons which is the subject of this post. In order to provide some context, June 2012 was the wettest recorded June in 54 years with 130mm of rainfall which is almost double(196%) the average rainfall for the month and July is the fourth wettest with 75% more than average. Apart from this year...

Here Comes the Rain - Part 1

Summer 2012 may be remembered for the Olympic Games. Or it may be remembered for the rain. From doom laden predictions of the worst drought for a generation in the southern half of Britain with disastrous consequences for farmers in the spring to torrential rain, floods and, yes, disastrous consequences for farmers in the summer. The burning question is whether this is just the natural variability of weather or whether underlying climate change has a hand in driving these weather systems. To investigate this question, I have studied some local weather records. My statistical skills are about High School level: mean and standard deviation of a normal distribution. Data for Glasgow Airport from 1959 to 2012 was obtained from the  Meteorological Office website but the 2012 data was discarded as it is only provisional and represents an incomplete year. The data included monthly rainfall, sunshine and maximum and minimum temperatures and the focus of this study was the rainfall data. ...

When the Wind Blows

How the mighty have fallen - Mature tree in Pollok Park destroyed in December storms It has been fairly windy in Scotland over the past year. Back in May , unseasonable storms battered the country causing one fatality, power outages, travel disruption, damage to crops  and felling many trees.  We do not normally have such high winds during the spring and summer when the trees are in full leaf so they were more susceptible to damage and many mature trees were lost. The next big storm was in September when the tail end of Hurricane Katia brought heavy rain, flooding and more trees down. It was not nearly as severe as Huricane Irene that struck the north east US a couple of weeks earlier but it still caused at least one fatality and significant disruption. A relatively calm and mild but wet autumn followed as local government prepared for heavy snow like that which caught them out last year. Then came hurricane force winds on the 8th of December . They had been f...
