iStockphoto/Thinkstock(NORMAN, Okla.) — Just two years after the worst 12 month period for EF1 or stronger tornados in U.S. history, the country got a big break, as new research from the National Oceanic and Atmospheric Administration shows that last year saw a record low number of severe twisters.

From May 2010 to April 2011, the United States was hit by over 1,000 big tornados, causing more than 535 deaths. The most recent period, from May of last year until this past April, saw only seven tornado fatalities, and less than 200 tornadoes recorded.

According to Harold Brooks, a scientist with the National Severe Storm Lab in Norman, Oklah., it’s “the fewest number of tornado fatalities in a 12 month period since the 19th century.”

Scientists have data about tornados and tornado-related deaths going back to 1954.

Why has the nation been so lucky on this front compared to two years ago? Experts say that a hot summer and a cold winter are factors.

“In the summer-time, when it’s very hot, what we tend to have is the jet-stream is located far north into Canada, and it tends to be very dry at the surface, that’s why we have droughts,” explained Brooks. “When the jet-stream is that far north, the change in the winds with height is weak over the middle part of the country and so none of the ingredients come together to produce the kinds of environments we want to have for tornadoes.”

Burke/Triolo Productions/Comstock/Thinkstock(NEW YORK) — Last year was a brutally hot one in the contiguous U.S.

Not only did the average temperature of 55.3 degrees prove to be the hottest recorded by the National Oceanic and Atmospheric Administration, beating the 1998 record by one degree, but that same temp was 3.2 degrees higher than the 20th-century average.

Dialing it back to the previous year, NOAA said the 16-month stretch from June 2011 through September 2012 featured above normal temperatures during each of those months — the longest period of higher-than-normal heat since records started being kept in 1895.

And if you’re thinking this has something to do with climate change, federal scientists are telling Americans to go right ahead and think that because it’s what they believe too.

Thomas R. Karl, who directs NOAA’s National Climatic Data Center, says we should expect to see periods of sustained warmth from here on in, adding, “That doesn’t mean every season and every year is going to be breaking all-time records, but you’re going to see this with increasing frequency.”

This also means that a pledge by world leaders in 2009 to keep global temperatures from rising above pre-industrial levels by 3.6 degrees Fahrenheit before the end of the century is likely not possible.

NASA GOES Project(NEW YORK) — The 2012 hurricane season, a time period that produced 19 named storms, including 10 hurricanes and one post-tropical cyclone called Sandy, officially comes to an end on Friday.

The National Oceanic and Atmospheric Administration (NOAA) says 2012 was an above-average year for storms.  The average annual number of named storms is 12, with six being the average yearly number of hurricanes.  The hurricane season runs from June 1 to Nov. 30.

The past season marks the second consecutive year that the mid-Atlantic and Northeast suffered devastating impacts from a named storm: Sandy this year, and Hurricane Irene in 2011.

This year also included tropical storms Beryl and Debby in Florida and Hurricane Isaac in Louisiana.

Sandy was not officially a hurricane when it made landfall in New Jersey last month — it is officially categorized as post-tropical Cyclone Sandy — but it certainly delivered hurricane-level death and devastation.

New Jersey is asking the federal government for some $30 billion in aid to help rebuild, while New York state has petitioned Uncle Sam for $39 billion in rebuilding assistance.

Laura Furgione, acting director of NOAA’s National Weather Service, says this year proves that it’s “wrong to think that only major hurricanes can ruin lives and impact local economics.”

NOAA notes that for the seventh consecutive year, no major hurricanes — those storms labeled Category 3, 4 and 5 — hit the U.S.

The only major hurricane this season was Hurricane Michael, which was a Category 3 storm that stayed out in the Atlantic.

The federal agency says it will release its pre-season outlook for the 2013 hurricane season in May.

NOAA Okeanos Explorer Program(NEW YORK) — Scientists have discovered a 19th-century shipwreck off the coast of the Gulf of Mexico. They made the find during an expedition led by the National Oceanic and Atmospheric Administration and the Bureau of Ocean Energy Management.

Researchers, working from the NOAA ship Okeanos Explorer, found remnants of a wooden-hulled vessel that is believed to be about 200 years old.

Using underwater robots and high-definition cameras, scientists found a wealth of artifacts, including anchors, navigation equipment, glass bottles, ceramic plates, an iron stove, cannons and a box of muskets.

“This discovery was part of a larger mission to look at unknown or poorly-known areas in the Gulf of Mexico,” said Frank Cantelas, a maritime archaeologist with NOAA’s Office of Ocean Exploration and Research.

According to NOAA, “the 56-day expedition that ended April 29 was exploring poorly known regions of the Gulf, mapping and imaging unknown or little-known features and habitats, developing and testing a method to measure the rate that gas rises from naturally-occurring seeps on the seafloor, and investigating potential shipwreck sites.”

Using sonar technology, researchers had a first look last fall at what turned out to be the site of the shipwreck.

According to Cantelas, Shell Oil Company was conducting an oil and gas survey required by the government to be sure none of its projects are disturbing anything sensitive in the ocean.

“The site is in over 4,000 feet of water and we knew nothing about it — we just had a fuzzy image from a sonar recording, which is like a camera but uses sound instead of light,” Cantelas said. “But we wanted to see what it was because it was shaped like it could be a shipwreck.”

So NOAA partnered with the Bureau of Ocean Energy Management (BOEM), which issues permits for bottom-disturbing activities related to oil and gas exploration, to find the 200-year-old shipwreck.

The ship used telepresence technology to transmit what was happening on the ship live.

“Telepresence provides the ability to bring a lot of different specialists, who have various expertise, to the table during the dive,” said Fred Gorell, public affairs officer for NOAA’s office of Exploration and Research. “They could actually look at the wreck sites while it was happening. And this way research is not limited by the number of people who are actually on the ship.”

“Artifacts in and around the wreck and the hull’s copper sheathing may date the vessel to the early to mid-19th century,” said Jack Irion, a maritime archaeologist with BOEM, in a NOAA statement. “Some of the more datable objects include what appears to be a type of ceramic plate that was popular between 1800 and 1830, and a wide variety of glass bottles. A rare ship’s stove on the site is one of only a handful of surviving examples in the world and the second one found on a shipwreck in the Gulf of Mexico.”

And researchers hope this discovery will help in other areas.

“Archaeologically, this is a very significant find,” Cantelas said. “It appears to date back to the early 1800s and a lot was going on in the Gulf of Mexico around that time. You have the Louisiana Purchase, the Texas Revolution, the Mexican-American War — a lot of conflict in that region — so this research will hopefully help us fill in the blank pages of history. It will provide information that we don’t really know about the history of the Gulf region.”

NOAA/Storm Prediction Center (WASHINGTON) — The National Oceanic and Atmospheric Administration’s Storm Prediction Center issued a rare “high risk” alert on Friday, warning of the potential for severe thunderstorms and tornadoes across Midwestern states over the weekend.

The biggest threat is to Oklahoma and Kansas, but states as far north as Nebraska and as far south as Texas could also be in danger.  The storms are expected to intensify Saturday afternoon into the evening, when a tornado outbreak is likely to occur.

The storm system in question is currently moving through California, where it is bringing hail and lightning to San Francisco and Sacramento, and three feet of snow to the mountains.

The last time the Storm Prediction Center issued such a high risk this far in advance was in April 2011, ahead of a tornado outbreak in Alabama that killed over 300 people and produced billions of dollars in damage.
