Figure 3. Winter (Dec to March) temperatures at Stykkishólmur. The red line corresponds to a linear trend of 1.2°C per century.
We also see that the individual warm and cold winter periods are similar to the corresponding annual ones in temporal behaviour. There are a few warm winters during the 19th century warm period with temperatures

5, 6, 9, 12 and 24 hours of the eruption. The green dots indicate the median lightning
locations and the red dots the locations after a simple wind correction with a time
constant of 500 s. Four hours into the eruption (at 22:00 UTC) the wind corrected
estimates are all within 1 km of the actual eruption crater.
