Understanding the complex order behind the apparent chaos of a tropical storm or hurricane is no easy task, but it s worthwhile to try — such storms deal death and destruction globally, and the better we know them, the better we can prepare for them.A NASA blog post highlights some of the work and improvements done in storm prediction and simulation being done at the Global Modeling and Assimilation Office.In the model we basically transform Earth s atmosphere into little cubes and in each cube the fundamental equations controlling motion, energy and continuity of the atmosphere are solved, said GMAO meteorologist Oreste Reale in NASA s post.As an illustration of how far models have come, here are two models of Hurricane Katrina, one from 2005 and one from 2015:The higher resolution isn t just for looks, either.2005 models drastically underestimated the atmospheric pressure levels the storm would reach; 2015 models come much closer.If it s simple, chances are it s not true.
Meteorologists are getting better at predicting hurricanes because our ability to model the atmosphere has improved dramatically.Modern forecasters use computer models of the atmosphere to help them figure out what the weather will do next.Freshwater floods, often caused by hurricanes, are the number one cause of death by natural disasters in the world, even above earthquakes and volcanoes, Goddard tropical meteorologist Oreste Reale said.We are able to use cases like Hurricane Katrina to run tests and show us how we can improve, or how this new change affected the forecast or the analysis of the storm system, fellow Goddard tropical meteorologist Marangelly Fuentes explained.Reale and Fuente s modeling can now get much closer to that actual pressure in attempting to model the storm, which in turn produces better forecasts.They are also able to model at a much better resolution, further increasing accuracy.
This February, 2016 photo released Monday, May 30, 2016 by ARC Centre of Excellence for Coral Reef Studies shows mature stag-horn coral bleached at Lizard Island, Great Barrier Reef off the eastern coast of northern Australia."We're talking about losing 35 percent of the population of coral in some of these reefs — that's huge."Experts say the bleaching has been triggered by global warming and El Nino, a warming of parts of the Pacific Ocean that changes weather worldwide.The remnants of the storm which had lashed the South Pacific brought cloud cover and heavy rains to the region, cooling the ocean enough to stop bleaching that had just begun in the south.About 95 percent of the coral in the southern portion of the reef has survived.Last year, the United Nations' heritage body expressed concern about the state of the Great Barrier Reef and urged Australia to boost its conservation efforts.
The Mighty Hercules, capable of flying about 18 hours without refueling, has been the mainstay of the US Air Force s Hurricane Hunters program since 1999.Galveston's most memorable hurricane is the Great Storm of 1900, which caused an estimated 6,000 to 12,000 fatalities and is still the deadliest natural disaster in US history.Such a rotation, in addition to maximum sustained winds of 39mph 35 knots , is required for the National Hurricane Center to name a storm.After flying through all four quadrants of the storm to ensure that there is indeed a closed circulation, the mission will then attempt to get a fix on the center of circulation.For our tour, however, the cargo compartment was largely empty except for Captain Luke Caulder, who stood by to answer any questions.The Gulfstream IV, managed by NOAA, visited Galveston's Scholes Field along with the Mighty Hercules.
Doing sprint intervals on a running track or the treadmill at the gym is a popular way to get an effective, short cardio workout.There s one major gripe: you re mainly working out your legs.Then you rest for a set time period before repeating.During a hurricane sprint, you would include a core like a plank or bicycle crunches or upper body movement like a push-up or row in place of your rest periods, as this article at Roman Fitness Systems writes:If you ve never done hurricane sprints before, here s what I would start with:A1 Sprint, 3 x 20 secondsA2 Pushups, 3 x 20Rest: 2 minutesB1 Sprint, 3 x 20 secondsB2 Dumbbell rows* both arms at once , 3 x 15Rest: 2 minutesC1 Sprint, 3 x 20 secondsC2 Plank, 3 x 30 secondsMy note here is that if you don t have a dumbbell for rows, try doing inverted rows on a low-hanging bar at the park, or use a door.You should only do this workout once a week, and fair warning: it s only 15-20 minutes, but the workout is going to suck.Why You Need to Be Doing Hurricane Sprints Roman Fitness Systems
If you read anything about Typhoon Nepartak, it probably will mention early on that it was the strongest storm to make landfall on Taiwan in 45 years.And yes, wind speeds topping 150 mph are very impressive.Of all the things that pose threats to people in the path of a tropical cyclone—rain, storm surge, flooding—wind is near the bottom.Yet it is central to every major cyclone classification system.It worries me that we focus on scale and category when what we know from hurricanes and trop cyclones in general we see most of deaths from water, says Marshall Shepherd, director of atmospheric sciences at the University of Georgia.He s referring to the various scales used to measure storm intensity.
The most destructive part of a typhoon isn t the wind.Even after being weakened to a tropical storm, Typhoon Nepartak dumped torrential rain on Taiwan and China.This astonishing shot of debris choking a bridge in the Fujian province city of Bandong Town shows just how devastating it was.Nepartak was the first typhoon of a season that began in May.It started brewing on July 2 and hit Taiwan five days later with winds approaching 150 mph, making it a Category 4 super typhoon.Nepartak weakened to a tropical storm after landfall, but still carried tremendous moisture.
On Thursday some meteorologists who are by nature a cheesy lot had an opportunity to channel their inner Dixie Chick and sing "Goodbye Earl" as yet another hurricane went into the Yucatan Peninsula to die.Most of the rest of the United States yawned—another hurricane in the Atlantic, and no harm done.But the hurricane was remarkable precisely because of this.Earl, which attained a maximum wind speed of 80 mph before striking Belize, marked another in a long line of hurricanes that have formed in the Atlantic basin—the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico—but have not affected the United States.Consider some of the following statistics: the last hurricane to reach the Gulf of Mexico was Ingrid in September, 2013.The current, nearly three-year-long drought for the Gulf has not been equaled since at least 1851.
Along Honey Cut Bayou, in eastern Baton Rouge, just north of Interstate 12.The first damage analysis of the slow-moving tropical system that deluged southern Louisiana last weekend is sobering.But for all the destruction it has caused, the low pressure system was not classified as a tropical storm or depression.Had it been a tropical cyclone, the storm would almost certainly rank among the 10 costliest hurricanes to strike the United States.The analysis uses geographic information system data to study homes and businesses that had flooded in nine parishes in southeastern Louisiana.Some of the report's key findings include:
Hurricane Madeline left and Lester right churning toward Hawaii on Monday.Image: NASA via Weather UndergroundIn what s being hailed a meteorological first, two back-to-back hurricanes are marching toward Hawaii, both of them threatening torrential rains and rip-roaring winds this week.The closer of the two, hurricane Madeline, could break a second meteorological record as the first hurricane to strike the Big Island since bookkeeping began in 1949.Rumbling west at approximately 9 mph, Madeline is currently packing Category 3 windspeeds of 120 mph.Its latest track has the storm passing south of the Big Island on Thursday, although as meteorologists Bob Henson and Jeff Masters point out over at Weather Underground, it s too early to rule out the possibility of landfall on the island of Hawai i.
Tropical storm Hermine forming in the Gulf of Mexico yesterday.Millions of Americans are preparing for a wet and wild Labor Day weekend as Tropical Storm Hermine bears down on the southeast, threatening to dump up to ten inches of rain over portions of northwest Florida and southern Georgia through Friday.The storm, which NOAA s National Hurricane Center upgraded from a tropical depression late yesterday, continues to intensify and could attain hurricane strength by the time it makes landfall later today.Hurricane and tropical storm warnings and watches are in effect for parts of northwest Florida, southwest Georgia, and eastern Alabama.GIF Image: National Hurricane CenterAfter making landfall, Hermine is on track to march up the coast in a northeasterly direction, possibly delivering tropical rains as far north as Boston by the weekend.
The good news is that a modern hurricane will probably not directly kill you.Our ancestors had to deal with a world that lacked satellites, television news, and Twitter.You are a modern person of some means, and so if you die in a storm there s a decent chance you ll be killed by generators, chainsaws, or electricity in a way that is neither heroic nor unavoidable.I have been trained to go door-to-door after a catastrophe to mark houses in a way that indicates if anyone inside is dead.Every storm is different, but there s a lot we can generalize.Redford refuses to do it, admitting he can t swim, which leads to Newman delivering one of the best movie lines of all time: Are you crazy?

Hermine continues to strengthen in the Gulf of Mexico, achieving hurricane status this afternoon.Image: NASA Goddard MODIS Rapid Response TeamAs Hermine continues to menace Florida s northwest coast, it officially crossed over into hurricane territory this afternoon.That makes this week rather special: Florida is about to get smacked with its first hurricane in more than a decade.For those who don t live in the Sunshine State, the words Florida and hurricane might feel rather synonymous.But for the past 11 years, the state has enjoyed a record hurricane-free streak.
The National Hurricane Center s latest forecast notes describe—with bureaucratic glee, if such a thing exists—a confluence of conditions that might lead to Hermine ripening into a hurricane as it travels towards the north Atlantic.Hermine made landfall early Friday morning on the Gulf Coast of Florida, breaking that state s 11-year hurricane drought.Since then, it has moved north—weakening, as these storms do when they travel over land.By the time you read this, it will probably have returned to the sea via one of the Carolinas.But besides the weakening, this storm is not behaving as expected.Very tall storms tend to have clouds with colder tops.
Hermine has an identity problem, shifting from hurricane to tropical storm to post-tropical cyclone.Whatever the heck it is it s already caused damage in Florida and power outages in Georgia, and South and North Carolina, and is expected to produce life threatening storm surges in New Jersey and New York over the course of today and tomorrow.And the name is not pronounced like her-MINE like the Harry Pottery character sans an O.The name is actually the feminine form of Herman, and reached peak popularity at the turn of last century.According to the National Oceanic and Atmospheric Administration it is pronounced her-MEEN.Hermine has appeared on NOAA s list of potential storm names since the permanent naming scheme was developed in 1979.
GIF Hermine s eastward move Image: GIF made from NOAA satellite footage Post-tropical Cyclone Hermine took an unexpected veer east, which means that some of the worst of the rains and winds could happen out to sea if it continues on its trajectory.But even on that path, it could still send us a wave of storm surge floods.The National Hurricane Center s latest forecast shows Hermine continuing to move offshore and north through Monday—which is some good news, noted the National Hurricane Center s Director Rick Knabb in a briefing this morning.But, the move could also trigger Hermine to develop hurricane-force winds tonight and Monday due to the warmer waters it will travel over, which could push water to the shores even harder.NHC is warning that rising waters could bring life-threatening inundation over the next 36 hours.
Until Hermine blew through the Florida Panhandle and up into Georgia, Florida had experienced a pleasant, hurricane-free few years.In fact, as The Weather Channel noted, Florida went nearly eleven years without a single hurricane making landfall.The last hurricane to set foot in Florida was Hurricane Wilma, a Category 3 storm that made landfall in south Florida back on October 24, 2005.Since then 68 Atlantic-based hurricanes have skipped the Sunshine State—more than twice the previous record of hurricanes.That s alarming as, according to the National Hurricane Center, 40-percent of Atlantic and Gulf-based hurricanes from 1851-2010 affected Florida.The state has more coastline than any other state touching the Gulf of Mexico or the Atlantic, so the odds were never in Florida s favor.
North Korean workers build levees along a river bank in an undated image from a video released by state media on Monday.In a rare admission that life isn t paradise within its borders, North Korea is asking for international aid in wake of devastating floods that state media claims to have impacted tens of thousands.Information released Sunday by the United Nations Office for the Coordination of Humanitarian Affairs confirms that North Korea is dealing with a big natural disaster.The flooding, which is concentrated along North Korea s northeastern border, was triggered by torrential rainfall brought on by Typhoon Lionrock, a powerful, long-lived tropical cyclone that impacted North Korea, Japan, and agricultural lands in China late last month.At least 133 North Koreans have been killed so far, 395 are missing, and over 140,000 are in need of urgent assistance, according to the UN.The timing of the disaster and the cry for help is a bit awkward.
Since yesterday evening, Hurricane Matthew has gathered strength and is on a collision course with the Caribbean.Here s what we know about the strongest hurricane to hit the region since 2007.Matthew hit Category 5 in the early hours of Saturday morning, becoming the first to do so since Hurricane Felix in 2007.It has dipped back down to a category 4 now and is still estimated by the National Hurricane Center in Miami to have winds of 155 mph.This morning, the hurricane briefly drenched Colombia as a it went through the northern tip of South America.Heavy flooding was reported and authorities say at least one person is dead as a result of the storm.
