2016. The map below shows rainfall totals in mm for the period from 1 November 2015 to 13 January 2016 inclusive. Across lowland England, rainfall totals were near average but most of Wales, northern England, Northern Ireland and Scotland received at least 500mm, with several rain-gauges including

flux was constant to within a factor of two. Since Karen’s work several authors have verified that the tendency of spots to occur at the same position repeatedly was not chance. Also they have shown that at least half the flux that emerges on the solar surface occurs in these clusters -nests-centers

) and a stormy westerly (Pattern 20). Patterns are ordered according to their annual historic occurrences between 1850 and 2003, which was the period used to generate the patterns. Pattern 1 occurs most often annually (around 6.5% of the time) and Pattern 30 occurs least often annually (around 1.5

will remain a dominant driver of global weather patterns over the next few months at least, more especially for tropical regions. With a couple of notable exceptions (e.g., East Africa) La Niña, very broadly speaking, tends to increase the likelihood of wetter than normal conditions across many land

/ downscaling methods rather than raw model output. • Bias-correction methods require sufficient observational data to characterize the reference climatology. In practice, this is at least 10 years of data (often 30 years) in order to include some variations at the decadal timescale. • The quality

above pre-industrial levels. In modelled scenarios that achieve this, the rise in atmospheric CO2 slows rapidly and ceases completely within the next two decades. The IPCC 6th Assessment Report included 3 scenarios which have at least a 50% likelihood of limiting global warming to 1.5°C with little
