There is clearly a good deal of variation in the inherent predictability of tropical
cyclone track from one case to another.

10 years of
cyclone track data

They then compared the results
from their new formula to actual
cyclone intensification data at each location along tropical
cyclone tracks in the Atlantic, Eastern Pacific, and Northwest Pacific for the 10 - year period 2004 through 2013.
To attack this information gap, the research team analyzed 30 years of tropical

With the improvements in forecast, 24 - hour
track and intensity forecast error of the tropical
cyclones reduced
from 141 km to 97 km and «landfall error»
from 99 km to 56 km during 2006 to 2015.
Further complicating the use of these proxies is the fact that the deviation in oxygen - 18 ratios is affected by the amount of TC rainfall, the distance
from the center of the
cyclone at which the rain was produced, and the intensity of the
cyclone — so I doubt these proxies alone will enable disentangling intensity and rainfall, tnough a large number of samples over an area could reveal information about the
track and extent of the TC event.
AER scientists have developed techniques to process an ensemble of over fifty tropical
cyclone track forecasts
from all leading US and international hurricane modeling centers.
The team then compared the oxygen isotope ratio for each year's wet season
from 1990 to 2010 with a
cyclone activity index of the average accumulated energy expended, based on factors such as number of
cyclones,
cyclone strength, size and time on storm
track.
Not only does this low - pressure area, or
cyclone, look bigger, more intense and longer - lasting than the one
from last year, the ice also seems to be in a weaker state than ever, as evidenced by the fact that 2012 trend lines on both sea ice area and sea ice extent graphs
track lower than previous record years, despite weather that until recently would completely stall the decline.
The researchers compared the GNSS - R satellite measurements with data
from other sources, including tropical
