Sentences with phrase «cyclone activity from»

an improved understanding of interannual variability and trends in the tropical cyclone activity from the beginning of the 20th century to the present

The US CLIVAR Hurricane Working Group was formed to improve understanding of interannual variability and trends in the tropical cyclone activity from the beginning of the 20th century to the present and quantify changes in the characteristics of tropical cyclones under a warming climate.

They add that this slow pace currently makes the trend undetectable due to inadequate long - term records and the considerable variance in cyclone activity from season to season.

Not exact matches

«With the hydrological cycle projected to change under global warming, impacting upper - ocean stratification and mixing, the results from this study have potentially important implications for understanding future tropical cyclone activity.»

Hope every goverment do not escape mandatory limit to greenhouse gases, see global warming like this time Myanmer's cyclone, to rescue our earth from global warming, activity, positively.

Adam G: You can not conclude that just from looking at a basin which has less than 15 % of the total global tropical cyclone activity, and also selecting groups of years that coincide exactly with the positive and negative Atlantic Multi-decadal Oscillation phases, which would dominate over any AGW trend in this basin if it exists.

# 57 Solar activity (if you mean TSI) has no clear trend from 1980s (if any, less pronounced than the difference bewteen a minimum and a maximum in a cycle, and I'm not informed of a statistical link between solar cycle variation and cyclone activity).

«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.»

The two correlated well, enabling the team to calculate the cyclone activity index from stalagmite data for the past 700 or 1500 years, depending on the stalagmite.

Rainfall from cyclones contains relatively little heavy oxygen so analysing the oxygen isotope ratio of calcite in stalagmites can reveal the extent of cyclone activity.

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.

Therefore, it remains uncertain whether past changes in tropical cyclone activity have exceeded the variability expected from natural causes.

In a study published in the journal Climatic Change, scientists Michael Chenoweth and Dmitry Divine analyze the history of tropical cyclone activity in the Lesser Antilles from 1638 to 2009.

The southern hemisphere tropical cyclone season normally runs from November to April and so far this season activity in the South Pacific Ocean has been relatively low.

Apart from wreaking havoc and killing a lot of people, Bopha's main effect was to nudge annual cyclone activity back up towards something approaching the long - term norms.

Indeed, Klotzbach has shown (23) that extreme tropical cyclones and overall tropical cyclone activity have globally been flat from 1986 until 2005, despite a sea surface temperature warming of 0.25 Â °C.

How to they «smooth» / eliminate the variation of cyclone activity which peaked from 1991 to 1999?

In terms of historical tropical cyclone activity, a 2010 WMO assessment of tropical cyclones and climate change concluded that «it remains uncertain whether past changes in tropical cyclone activity have exceeded the variability expected from natural causes.»
