The variation of Atlantic hurricanes relative to hurricanes
in other basins in the context of known cycles of natural variability needs further investigation.»
The vertical scale in the West North Pacific is twice as large as that
of other basins.
Schultz and his colleagues used similar methods to estimate the sizes of impactors related to
several other basins on the Moon created by oblique impacts.
Once this threshold is passed, rapid ice sheet collapse could occur, which would spill over
into other basins and perhaps spell an end for the West Antarctic Ice Sheet.
In separate calculations, I obtain similar results by optimizing the pattern in distinct basins individually and then estimating the pattern in
other basins by regression, suggesting that the global, same - sign character of the pattern is not an artifact of the EOF truncation used in the analysis.
This is a clear disconnect that in all fairness should be considered before stating that our algorithm «doesn't work well
in other basins».
If you do this, be sure to do it in a large bucket or
other basin.
On a contrary note, I worry that Gavin may have missed a key point of our research when stating (in the introduction above) that our technique «doesn't work as well in
the other basins».
The best track from
the other basins are constructed at JTWC by temporarily assigned military personnel, many of whom have no experience whatsoever with hurricanes.
It would be easy enough to test whether the storms in
other basins had different characteristics by also performing an EOF analysis for each region.
This to me implies a strong need for aerial recon in
other basins, particularly the NW Pacific, which has the highest frequency of the category 4 & 5 storms that primarily fuel the debate.
Given the different land - sea configurations and the different role of ENSO in the different basins, and the fact that disturbances in
other basins do not form from easterly waves from off of Africa, there is every reason to expect that storms in other basins have different characteristics.
Well, it confirms the large trend in the North Atlantic (seen in Emanuel, 2005), but doesn't show significant trends in
the other basins (from 1983).
States that while no significant trends have been identified in the Atlantic since the late 19th century, significant observed trends in TC numbers and intensities have occurred in this basin over the past few decades, and trends in
other basins are increasingly being identified
No studies had revealed an upward trend of hurricane frequency or intensity — not in the Atlantic basin — or in
any other basin.
«There could be 20 billion barrels of oil equivalent left to exploit but the UK competes against
every other basin in the world for investment and I am committed to make sure that we have a licensing regime and investment environment that attracts quality companies and investment to fully exploit the remaining potential.
However, at some point it would be preferable to re-derive the Dvorak technique to calibrate tropical cyclones with available data in
the other basins.
Having said that, similar changes in tropical cyclone detection also seem to have occurred for each of
the other basins, e.g., Hoarau et al., 2012 (Abstract) suggest that incomplete satellite coverage during the 1980s and early 1990s led to an underestimation of cyclone intensity in the northern Indian Ocean basin.
While the Dvorak technique was calibrated for the Atlantic and Northwest Pacific basin because of the aircraft reconnaissance data ground truth, the technique has also been quite useful in
other basins that have limited observational platforms.
The data extend back to 1944 for the North Atlantic, to 1950 for the northeastern Pacific, and to 1970 for
the other basins.
The results of the combined sampling showed an optimal mean leakage rate of 0.4 percent of production, which the researchers noted is «significantly lower than rates found using top - down methodology at
any other basin.»
However, an important question concerns whether global warming has or will substantially affect tropical cyclone activity in
other basins.
