Sentences with phrase «tropical cyclone season»

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.

«We foresee another very active Atlantic basin tropical cyclone season in 2006,» states a report from a team including long - time forecasting guru William Gray of Colorado State University.

It has been an unusually quiet tropical cyclone season in the Southern Hemisphere this year, as we discussed in detail in a February 28 post.

TheWashington Post's Jason Samenow described it as «the most extreme tropical cyclone season on record in the Northern Hemisphere.»

These events included historic droughts in East Africa, the southern United States and northern Mexico; an above - average tropical cyclone season in the North Atlantic hurricane basin and a below - average season in the eastern North Pacific; and the wettest two - year period (2010 — 2011) on record in Australia.

The Central Pacific also saw an above - average tropical cyclone season, with 14 named storms, eight hurricanes, and five major hurricanes, the most active season since reliable record - keeping began in 1971.

It is the strongest storm of the 2005 - 06 Southern Hemisphere tropical cyclone season thus far, and one of the strongest tropical cyclones ever recorded in the Southern Hemisphere.

Accumulated cyclone energy (ACE) is a measure used by the National Oceanic and Atmospheric Administration (NOAA) to express the activity of individual tropical cyclones and entire tropical cyclone seasons, * particularly the North Atlantic hurricane season.

Gabriele Villarini, UI associate professor of civil and environmental engineering and corresponding author on the paper, says researchers honed in on predicting the impacts of tropical cyclones because that information is generally more useful than typical forecasts that predict how many storms are expected in a season.

Webster is now studying the duration of the hurricane season each year, from the first tropical cyclone to the last.

With the Nov. 30 end of the 2014 hurricane season just weeks away, a University of Iowa researcher and his colleagues have found that North Atlantic tropical cyclones in fact have a significant effect on the Midwest.

The ACE index is used to calculate the intensity of the hurricane season and is a function of the wind speed and duration of each tropical cyclone.

The Accumulated Cyclone Energy (ACE) index of tropical cyclone activity also indicated a below - average season in the North Atlantic.

The number of tropical cyclones was more than the eight that occurred during the 2014 season.

NOAA has issued its annual forecast for the hurricane season, along with its now - standard explanation that there is a natural cycle of multidecadal (40 - 60 year) length in the North Atlantic circulation (often referred to as the «Atlantic Multidecadal Oscillation» — see Figure), that is varying the frequency of Atlantic tropical cyclones, and that the present high level of activity is due to a concurrent positive peak in this oscillation.

Those conditions just tend to be more favorable during the officially recognized six - month season, which encompasses about 97 percent of tropical cyclone activity in the Atlantic.

According to Accuweather, however, hurricane season in the Central Pacific lasts from approximately June 1 to November 3, with the chances of a tropical cyclone peaking in August.

Summer (Green Season): December - February These months sometimes experience the highest rainfall, and can also be accompanied by thunderstorms and the occasional tropical cyclone.

The clear seasonality in TCs («hurricane season») with highest activities during the summer is one of the strongest pieces of empirical evidence that higher temperatures give more favourable conditions for tropical cyclones (After all, TCs only form in the warm tropics...).

NOAA also forecasts a high hurricane activity for the remainder of the season, and time will show if this season will match the 2004 in terms of number of tropical cyclones.

I wonder if the fact the higher SSTs will lead to somewhat longer seasons (and 2005 certainly had that), and larger sea - surface area where TCs might form, would serve to counteract the effect you describe, and still lead, net - net, to an increase in the number of tropical cyclones with higher SSTs.

In addition, statistics on the seasons of tropical cyclone genesis and their landfall locations from AD 1945 — 2013 in the Northwest Pacific Ocean region reveal that in summer, tropical cyclones tend to make landfall along coastal regions north of Fujian Province, eastern China; however, in autumn and winter, cyclones tend to be guided further southward to make landfall in southern China (Hainan), Vietnam, and the Philippines.

For example, as I mentioned in the earlier post, wind shear can cap the rising air in a cyclone, choking it off, preventing a full - blown tropical cyclone from forming — this is one reason we've seen fewer hurricanes in the Atlantic this season.

«In the North Atlantic region, where tropical cyclone records are longer and generally of better quality than elsewhere, power dissipation by tropical cyclones is highly correlated with sea surface temperature during hurricane season in the regions where storms typically develop»

As NOAA explains «The ACE index is used to calculate the intensity of the hurricane season and is a function of the wind speed and duration of each tropical cyclone.»

It could be a simple event such as extreme precipitation or a tropical cyclone or a more complex sequence of a late onset of the monsoon coupled with prolonged dry spells within the rainy season.

As the ITCZ migrates more than 500 kilometres (300 mi) from the equator during the respective hemisphere's summer season, increasing Coriolis force makes the formation of tropical cyclones within this zone more possible.

Add a four - month annual monsoon season and top off with a climate change - driven sea level rise and more frequent, powerful tropical cyclones, and you're looking at catastrophic flooding.

The number of tropical cyclones during 2013 was slightly above average, but the North Atlantic Basin had its quietest season since 1994.

Unfortunately, despite this clear empirical evidence, the climate change and global warming doomsday alarmists attempt to portray the 2017 season as a sign of CO2 - induced climate catastrophe - and that is not being well accepted by the actual hurricane experts (here, here, here) who have been on the front lines of tropical cyclone activity and impact research.

If a noted climate scientist explains multi-year changes in ocean heat storage in terms of «tropical variablity» or «weather», I would suspect that any particularly intense tropical cyclone (or season, or multiple seasons) would surely also fall into this category of «tropical variability».

During the 13 hurricane seasons from 1982 to 1994, 71 (or about 5.5 per year) Atlantic Basin tropical cyclones passed over 28.25 ºC SST and 16 (or 22.5 %) of them, became major hurricanes.

Re # 112: «If a noted climate scientist explains multi-year changes in ocean heat storage in terms of «tropical variablity» or «weather», I would suspect that any particularly intense tropical cyclone (or season, or multiple seasons) would surely also fall into this category of «tropical variability».»
