2012 was the first full year of data for ArranWeather.com. The station is based in Sannox. The data does show a clear direction, and it’s not what you might expect…

Since 2012 there is a clear downtrend in the average annual temperature here.

We do have power cuts, phone line outages and damaging events here which do show in interruptions in the daily data, but taking into account a year at a time,removing the few days which there are issues causes a negligible difference the data.

Thankfully now after Snowmageddon, the power lines are much more resilient and we have far fewer power outages now.

It’s hard to pinpoint one specific thing which can cause a reduction in temperature, after all the Co2 levels in the world are on average increasing at a steady rate year on year. 2012 was the year Co2 concentrations passed 400ppm, and in 2020 we are now at 418ppm. It’s worth noting Co2 tends to peak in May each year.

It might come as a surprise to some but 2014 also coincided with a peak of a Solar cycle. It does make sense since the Sun is the greatest source of Earth’s energy for the climate. Changes in the Sun’s cycles are known to have an effect on Earth, the extent of which is still under discussion.

Something I’ve been working on is the cumulative sunspot effect (a running previous 58yrs average), the theory being that the energy from the Sun is stored in the oceans, and the ocean cycles this heat through many decades, which effects the climate further down the years. It’s a bit like having multiple outboard motors on your boat. If you turn one off there is still momentum from the other ones as well as the one you just turned off, and when you turn it on again, there is still a component of that momentum at play in the boats velocity.

Earth, the Sun, Solar System, the Galaxy and the Universe all work in cycles, so I set out to try and figure out some of the climate cycles.

Climate is a chaotic thing too research. Some areas react totally the opposite to global overall average, I might be right, I might be a wee bit right, or I might be completely and utterly totally wrong.

Science is there to be looked at and discussed 🙂

Wind and Rain data to follow…. some of it is as you can probably guess, some of it isnt!

N.B If anyone has daily temperature data (max & min) for a longer time span on Arran I’d be happy to have a look at the data and see what it shows.
