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.

There was 1 active category force storm during the week of the report. The trend lines for the chart for the 52 rolling weeks tipped downwards this week.

AMANDA Hurricane-4

AMANDA-track_2014-05-23

Strictly speaking if I was up to date with the reports this storm would not appear in this week’s report as it would only have been registering as a tropical depression at the time of the report end date.

This is reflected in the charts where the by day chart does not show the sorm at all as it had not reached category force.

Comparison of daily category attainment and duration category attainment

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 ****. 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.

Normally I do not publish the longer period charts I keep but this week I am showing the charts, as above, but for the period 22nd December 2011 to this week. As you can see there is a downward trend over this period about the equivalent to a 0.5 unit of category force. In other words the average force of category storms has dropped of this period from Force 2.5 to Force 2.

Regrettably I am unable to agree with the scaremongers that global warming is causing a significant increase in the number and intensity of category force storms! This really is hardly surprising as despite what the agenda may tell you that the dreaded CO2 is the cause of all our woes, it is actually the drop in the Sun’s output that is responsible for the downturn in category force storms, just as it probably is with earthquake which again despite the scaremongers on the blogs is actually at a decadal low.

I do however agree that we are undergoing climate change but it is climate change that is a normal course of events and not in any way associated with a trace gas in the atmosphere.
