Sentences with phrase «cyclone intensity data»

Cyclone Center's primary goal is to resolve discrepancies in the recent global TC record arising principally from inconsistent development of tropical cyclone intensity data.

Not exact matches

Of course, since hurricanes and tropical storms are all just degrees of intensity of the same type of storm — tropical cyclones — and since there are a very limited number of data points of one limits the data to hurricanes, it makes sense to include tropical storms.

«The IPCC hierarchy had its mind made up years ago to make every attempt possible to link rising levels of CO2 with increases in global hurricane intensity and frequency... Input from skeptics or any hypothesis or data that did not link rises in CO2 to increases in tropical cyclone activity was to be avoided, suppressed, or rejected.»

It's difficult to say what the trends are in cyclone intensity in the South Pacific, as only limited data are available since the 1980s.

Many previous studies» assertions about increases in global cyclone intensity were made without taking into account the quality of the data and have been largely dismissed.

Another presenter at the session, Paul Chang, a project scientist who studies satellite ocean surface wind data at the National Oceanic and Atmospheric Administration's Center for Weather and Climate Prediction in College Park, Md., said that the current method that is largely used by U.S. scientists in this area of research, known as the Dvorak technique, employs satellite imagery to estimate tropical cyclone intensity but is imprecise and subjective.

However, relevant questions linking tropical cyclones and lightning in the inner core remain: Considering the limitations of lightning data, the importance of environmental factors, and the changing climate, how significant is the information provided by episodic discharges in the inner core for forecasting the intensity change?

Together, the lightning and microwave data can track a range of parameters, including intensity changes in tropical cyclones; past research has shown that intensity changes are related to the density of lightning strokes [e.g., Solorzano et al., 2008; DeMaria et al., 2012].

While computer models suggested that global warming should cause an increase in cyclone intensity, e.g., Evans et al., 1994 (Open access), the historical data showed no obvious link between the intensity of a tropical cyclone and the temperatures where it formed, e.g., Evans, 1993 (Open access).

Similarly, as we mentioned in Section 2, Evans, 1993 (Open access) was unable to find any obvious link in the historical data between the intensity of a tropical cyclone and the temperatures where it formed.

States trends in tropical cyclone intensity of less obvious over the rest of the tropics due to data limitations

The Potential Intensity (PI) of tropical cyclones (Emanuel, 2003) can be computed from observational data based primarily on vertical profiles of temperature and humidity (see Box 3.5) and on SSTs.

The method is a way to estimate the maximum surface sustained wind over one minute which is the most significant data of a cyclone intensity.

«There is no compelling evidence to indicate that the characteristics of tropical and extratropical storms have changed... Owing to incomplete data and limited and conflicting analyses, it is uncertain as to whether there have been any long - term and large - scale increases in the intensity and frequency of extra-tropical cyclones in the Northern Hemisphere.

[1981] demonstrated that even when numerous ships and buoys are in a strong tropical cyclone, the actual intensity is likely to be drastically underestimated without aircraft or satellite data.
