2011 Was A Year of Weather Extremes, With More to Come

The global average temperature in 2011 was 14.52 degrees Celsius (58.14 degrees Fahrenheit). According to NASA scientists, this was the ninth warmest year in 132 years of recordkeeping, despite the cooling influence of the La Niña atmospheric and oceanic circulation pattern and relatively low solar irradiance. Since the 1970s, each subsequent decade has gotten hotter — and 9 of the 10 hottest years on record have occurred in the twenty-first century.

Each year’s average temperature is determined by a number of factors, including solar activity and the status of the El Niño/La Niña phenomenon. But heat-trapping gases that have accumulated in the atmosphere, largely from the burning of fossil fuels, have become a dominant force, pushing the Earth’s climate out of its normal range. The planet is now close to 0.8 degrees Celsius warmer than it was a century ago. Hidden within Read more…

US east coast on hurricane alert- New York City in direct path

The United States is on a high alert as Hurricane Irene builds momentum along its path from the Caribbean towards the US east coast.

“We’re going to have a very large tropical cyclone move up the eastern seaboard over the next five to seven days,” Bill Read, director of the National Hurricane Center, said on Wednesday.

But Read said it was too early to be certain where Irene would hit the coastline.

Latest data showed the hurricane strengthening back into a category two storm as it moved closer to Read more…

Fierce forecast: Feds predict up to 10 Atlantic hurricanes in 2011

Federal forecasters Thursday called for an “above-normal” hurricane season this year. They predict anywhere from 12-18 named storms to form in the Atlantic Ocean, Caribbean Sea and Gulf of Mexico.

Hurricane Earl spins in the Atlantic Ocean last September. Although it didn't make landfall, Earl came the closest to hitting the USA of any 2010 hurricane.Hurricane Earl spins in the Atlantic Ocean last September. Although it didn’t make landfall, Earl came the closest to hitting the USA of any 2010 hurricane.

Of those named storms, six to 10 should become hurricanes, including three to six “major” hurricanes, with wind speeds above 111 mph.

Tropical storms are given a name when wind speeds reach 39 mph. They are upgraded to hurricane status when their sustained winds reach 74 mph. An average Atlantic hurricane season sees 11 named storms, including six hurricanes; two become major hurricanes.

Forecasters do not predict the number of storms that will make landfall.

Climate factors in this outlook include unusually warm Atlantic Ocean water and temperatures two degrees above average, reports Gerry Bell, lead seasonal forecaster at the Climate Prediction Center. Additionally, the impacts of the La Nina climate pattern, such as reduced wind shear, are expected to continue into the hurricane season.

“In addition to multiple climate factors, seasonal climate models also indicate an above-normal season is likely, and even suggest we could see activity comparable to some of the active seasons since 1995,” Bell said.

Since 1995, Bell says the Atlantic is in an era of increased hurricane activity. There are consistently favorable ocean and atmospheric conditions for storm formation.

Thursday’s NOAA forecast is similar to earlier predictions by researchers at Colorado State University and the AccuWeather commercial weather service. The Colorado State team, led by Read more…

Forecasters expect 5 big hurricanes

Hurricane seasonAt least five major hurricanes with winds of more than 111 miles per hour are expected to develop in the Atlantic during the 2011 storm season, Colorado State University forecasters said yesterday.

Overall, some 16 named storms are likely, with nine of them reaching hurricane status — an above-average season, said the forecasters led by William Gray and Phil Klotzbach. The forecast reduces by one the group’s preliminary December outlook for 17 named storms.

There is a 72 percent chance that one of the major storms will strike the US coast, above the 52 percent average for the past century, they said, and a 47 percent chance of a Gulf Coast hit. The East Coast’s odds are 48 percent.

“We reduced the number of storms but our statistical models are still calling for an active Read more…

Tropical Cyclone Yasi Headed Toward Queensland, Australia

Tropical Storm Anthony made landfall in Queensland, Australia this past weekend, and now the residents are watching a larger, more powerful cyclone headed their way. NASA’s Terra satellite captured a visible image of the large Tropical Cyclone Yasi late yesterday as it makes its way west through the Coral Sea toward Queensland.

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard NASA’s Terra satellite captured an image of Cyclone Yasi on Jan. 30 at 23:20 UTC (6:20 p.m. EST/09:20 a.m., Monday, January 31 in Australia/Brisbane local time). Although the image did not reveal a visible eye, the storm appears to be well-formed and also appears to be strengthening.

Warnings and watches are already in effect throughout the Coral Sea. The Solomon Islands currently have a Tropical Cyclone warning for Read more…

Storms hit Western Australia southwest as cyclone nears

January 29, 2011 Comments off

Saturday afternoon’s storms caused damage in parts of Perth and regional towns to the east, including Toodyay, Northam, York and Wongan Hills.

State Emergency Service volunteers have responded to 20 calls for assistance in Perth for rain damage, localised flooding and roof collapses, the Fire and Emergency Services Authority (FESA) said.

In Northam and York, east of Perth, around 30 buildings were badly damaged, many with roofs torn off, and powerlines and other structures were also hammered, it said.

Between Northampton and Jurien Bay, north of Perth, there had been 18 calls for assistance for damaged roofs.

The stormy weather cut power to around 55,000 homes in WA’s south on Saturday as the category three cyclone Bianca approached across the Indian Ocean. Read more…

295,000 Deaths :950 Natural Disasters in 2010

January 5, 2011 Comments off

By: Munich RE

Jan. 3, 2011 – Several major catastrophes in 2010 resulted in substantial losses and an exceptionally high number of fatalities. The overall picture last year was dominated by an accumulation of severe earthquakes to an extent seldom experienced in recent decades. The high number of weather-related natural catastrophes and record temperatures both globally and in different regions of the world provide further indications of advancing climate change.

Altogether, a total of 950 natural catastrophes were recorded last year, nine-tenths of which were weather-related events like storms and floods. This total makes 2010 the year with the second-highest number of natural catastrophes since 1980, markedly exceeding the annual average for the last ten years (785 events per year). The overall losses amounted to around US$ 130bn, of which approximately US$ 37bn was insured. This puts 2010 among the six most loss-intensive years for the insurance industry since 1980. The level of overall losses was slightly above the high average of the past ten years.

“2010 showed the major risks we have to cope with. There were a number of severe earthquakes. The hurricane season was also eventful – it was just fortunate that the tracks of most of the storms remained over the open sea. But things could have turned out very differently”, said Torsten Jeworrek, Munich Re’s Reinsurance CEO. “The severe earthquakes and the hurricane season with so many storms demonstrate once again that there must be no slackening of our efforts to analyze these risks in detail and provide the necessary insurance covers at adequate prices. These prices calculated by the insurance industry make it possible to assess the economic consequences of these otherwise difficult-to-evaluate risks.”

Major catastrophes dominate the list of losses

In all, there were five catastrophes last year assignable to the top category of “great natural catastrophes” based on the definition criteria of the United Nations: the earthquakes in Read more…
