All the sections currently cover one storm, Martin. Use the form below to switch to the standard sections for another storm.
The sections below show: 1) details and statistics; 2) gust speed animation showing the track and instantaneous 3-second gusts at 3 hour intervals over a 72 hour period; 3) storm tracks showing the maximum in relative vorticity and minimum in MSLP, while labels on the maximum relative vorticity path indicate the start of that day; 4) raw footprint is described in Storm footprints; 5) uncontaminated raw footprint only includes gusts local to the storm (as described on Storm footprints); 6) observational footprint from MIDAS database; 7) recalibrated lower 95% bound is described in Recalibration of final storm footprints; 8) recalibrated mean is described in Recalibration of final storm footprints; 9) recalibrated upper 95% bound is described in Recalibration of final storm footprints; 10) raw models gusts versus observed gusts is described in Comparison of model footprints to station data; 11) recalibrated models gusts versus observed gusts showing the 95% bounds as error bars. Where data is available, links are provided under figure.
