7 July 2014: It is now Super Typhoon NEOGURI!

True to the forecast NEOGURI has now reached ‘Super Typhoon’ strength with maximum sustained 250 kph (~156 mph) winds, a category 5 in the Safir-Simpson Hurricane Wind Scale , gusting to 304 kph (~190 mph 3-sec gusts) as it tracks NNW  to the east of Taiwan.

Super-typhoon NEOGURI continues to track in a favorable ocean-atmospheric environment, which may promote further strengthening in the next 12 – 24 hours.

All interest around the Yellow Sea basin, from Taiwan and China, to Korea and Japan must monitor the progress of this super typhoon closely over the next couple of days at it carries the potential for causing severe damage  to buildings and infrastructure through the impacts of high winds, extreme rain, and storm surge.

UPDATE: 8 JULY 2014

Typhoon NEOGURI has weakened over the past few hours as it continues to move northward between northeastern Taiwan and southwestern Japan. The appearance of the storm has changed in satellite imagery, becoming more open with a larger eye. The forecast track has shifted slightly to the east. Osaka, Kyoto and even Tokyo appear to be in line with the projected track over the next couple of days.

Early Summer 2014: A panoramic view of Earth!

Early Summer 2014 on Earth’s northern hemisphere. Wherever you look  there are flashes of storms, extreme rain, flash floods and other disturbed weather events everywhere. It seems Mother Nature is experimenting with everything there is in  the atmosphere, including gigantic twin tornadoes striking simultaneously in the Heartland USA!

Let us take a look at what our satellites are seeing from above. The three images that follow are mosaics of satellite observations made earlier this Tuesday, 24 June 2014, with water-vapor filters, which  help highlight areas of storms and  disturbed weather.

The view above shows large storms over Texas and the Great Plains USA, a large area of storms extending from Northern South America over Panama, Costa Rica and Nicaragua. There is also a large cell off the coast of Central America and Mexico over the eastern east Pacific Ocean. And ‘Hurricane Alley’ shows a slim train of storm cells riding along on their westward journey. However, Equatorial Africa, which is the feeder for Hurricane Alley appears quiet and devoid of any major systems, but farther to the east over the Indian Ocean there are some major cells of tropical activity that may eventually find their way over Equatorial Africa to activate the ‘tropical wave assembly line’ in coming days.

The ‘belt of tropical activity’ appears much more active than over the Atlantic and Equatorial Africa on this view.  A train of large storm systems extends all the way from the Gulf of Panama in the east to the Philippines and beyond or more than 20,000 km. with only one significant gap to the southeast of Hawaii.

A rather different array of  weather systems is visible over the high latitudes in the southern hemisphere, where winter 2014 has just set in. A major weather system is clearly visible over New Zealand. However the other big islands south of the equator, Australia, Madagascar, are enjoying mostly clear weather during the earlier hours of this Tuesday 24 June 2014.

We all know however that it is just a question of time. Some of these cells in the northern hemisphere may start to show signs of cyclonic development, and in no time we may see a tropical cyclone over any of the basins that are cradles of cyclogenesis. So we keep on watching, looking for those early signs that allows us to investigate, and follow, and forecast. It is a never ending process between humans and Nature.

The most amazing aspect of this, one at which I always marvel, is that a rather insignificant weather cell over the central Indian Ocean just starting its westward journey. and a similarly anonymous storm cell over the Northwestern Pacific moving eastward along the fringes of a jet-strean may, not only survive their long journeys, but actually grow picking-up  strength and  size along the way, and get to interact with one another three weeks from today generating the next cyclonic event over the Atlantic, our neck-of-the-woods here in Florida.

Consequently, amazing as this view from above, and marvelous as the never-ending workings of the atmosphere and oceans are, the fact remains that we humans must always be alert, prepared and engaged in the practice of mitigation to reduce the potential for damage from that next one, which might be under gestation starting from opposite extreme of our planet Earth.

Enjoy today’s panoramic vistas. Keep on watching!
