Cyclone Climatology

Global Tropical Cyclone Frequency- 1971 to Present

Last 4-decades of Global Tropical Storm and Hurricane frequency — 12-month running sums. The top time series is the number of TCs that reach at least tropical storm strength (maximum lifetime wind speed exceeds 34-knots). The bottom time series is the number of hurricane strength (64-knots+) TCs.

Global Hurricane Frequency – 1978 to Present

Global Hurricane Frequency (all & major) — 12-month running sums. The top time series is the number of global tropical cyclones that reached at least hurricane-force (maximum lifetime wind speed exceeds 64-knots). The bottom time series is the number of global tropical cyclones that reached major hurricane strength (96-knots+). Adapted from Maue (2011) GRL.

Global Tropical Cyclone Accumulated Cyclone Energy (ACE) – 1971 to Present

Last 4-decades of Global and Northern Hemisphere Accumulated Cyclone Energy: 24 month running sums. Note that the year indicated represents the value of ACE through the previous 24-months for the Northern Hemisphere (bottom line/gray boxes) and the entire global (top line/blue boxes). The area in between represents the Southern Hemisphere total ACE.

Last 4-decades of Global Tropical Storm and Hurricane Accumulated Cyclone Energy — Annual totals. The Southern Hemisphere tropical cyclone season occurs from July-June each calendar year. The graph is constructed such that SH annual value for July 2014 – July 2015 is positioned in 2015.

Read about jet streams being accelerated by mid-latitude oxygen/ozone conversion which extends Rossby wave meander loops. Study this new theory on your desktop at this dedicated website:

still real useful page especially given the renewed interest in fomenting fear on climate change… notably now that coronafear is waning.

I’m hoping WUWT will be devoting some main blog time to the hurricane reporting by the NHC since last year’s kitchen sink tally of last year’s season.

I spent a bit of time cross-referencing the last Danny Public Advisory (#4) with on the ground weather reporting (via Weather Underground) and couldn’t find NHC’s maximum sustained winds and rainfall accumulation using Mobile, Huntsville, Montgomery, Atlanta, Macon, Savannnah. All locations I checked reported nothing more than 8 mph (range 1 to 8), and 0,25 inches of rainfall
(trace to 0,25) compared to the advisory’s MSW of 25 mph and 1″-3″ of rainfall.

Granted this is a tail’s end of Danny, but you’d think their observations would match up somewhere with ground observations. I’ll await the next one and catch it earlier to see what’s what. The trouble is that WU charts (shown using the 10 day weather presentation) isn’t available for more than 4 hours in the past.

Did the Saharan Air Layer tamp down TD formation during July? If so how long will it continue?

Whatever the cause(s), there will need to be 1 TD, 5 TS’s, plus 4 H’s in August to catch up to the 2020 season. I wonder if and how NHC will summarize July tomorrow.

This hurricane can cause catastrophic flooding.

Is there any possibility of getting dependable graphics for hurricane strength and frequency. This is a frequent claim that they are stronger and more frequent. Would love to be able to find a good graphic of TCE.
