Volcanoes

Volcano information gathered from various sources, including the Smithsonian Weekly Volcanic Activity Report from which confirmation of reports is taken. A volcano is only included in the listing if there is significant ash above 1km height (white/steam clouds are not counted) or there is a significant lava flow. Crater incandescence, unless accompanied by the either of the preceding does qualify as an eruption. The grey figures include the erupting numbers as well.

Comparison of daily category attaiment and duration category attainment
CFStorms_Dur-Day-Compare_20140425
(Click the Image for a larger/clearer version)

The comparison chart above shows the Category force storms as they are reported for the duration of the storm. This generally includes the lead in period as the storm builds and the lead out as it decreases to tropical storm or lower force, i.e. under category force.

The day element of the comparison only shows where a storm is reported as being category force. For any day that the storm is being reported as category force the higher of any force value is taken.

If we look at a storm such as ITA we can see that the storm duration was reported as from 04 April to 14 April. Up to 0600 Zulu (GMT/UTC) on 08 April the storm was a Tropical storm. During the 8th it was Cyclone 1 so for the 8th it is counted as one unit of force. Sown below as )

On the 9th it was one, rising to Cyclone 2 by the evening so it is counted as 2 )) for the day. On the 10th it was 4 )))) and on the 11th it was Cyclone 4 dropping to Cyclone 1 so the whole day is counted as Cyclone 4 4 )))). It was back to a tropical storm again on the 12th.

The comparison gives one a better idea than using just the duration since ITA was 11 days duration, but was only Category 4 on 2 of those days.
