The UK experienced unremarkable weather in all respects in Autumn 2020.
Last year, I predicted that the 2020 summer would not be good and I was right. On average it was duller, wetter and warmer than normal.
The UK experienced its sunniest spring on record in 2020 by a huge margin. Both April and May were the sunniest on record and together they resulted in an average of 6.5 hours of sunshine per day compared to the normal 4.5 hours per day.
The UK experienced its 5th wettest and warmest winter on record in 2020.
The UK experienced unremarkable weather in all respects in Autumn 2019.
The 2019 summer was the 7th wettest on record but was also unusually warm given the amount of rain that fell. I have made a prediction that summer 2020 will not be a good one!
The 2019 spring was consistent with the step change in the autumnal climate that took place in the 1990s but was unremarkable otherwise
The winter of 2019 was consistent with the step change in the winter climate that took place in the 1990s.
If I were to remark to you that “the weather is very nice today” or “I didn’t like that person”, it is unlikely that I would have made such statements based on a single variable. It is more likely that a combination of variables were evaluated to arrive at these statements. When we analysis datasets with multiple variables, we are undertaking Multivariate Statistical Analysis.
Multivariate Analysis comes in two flavours :-
- Analysis of Correlations between Multiple Variables – Known as R-Analysis – Informally known as reducing the dimensionality of your dataset.
- Analysis of Distance between Many Objects – Known as Q-Analysis – Informally known as mapping, clustering or segmentation of your dataset.
Meteorologists define autumn in the UK to be the period from September to November so autumn is now over and we are officially in winter. The 2018 autumn was consistent with the step change in the autumnal climate that took place in the 1990s.
