Adios El Nino, Hello La Nina?

The latest image of Pacific Ocean sea surface heights from the NASA/European Ocean Surface Topography Mission/Jason-2 oceanography satellite, captured on June 11, 2010, shows that the tropical Pacific has switched from warm (red) to cold (blue) during the last few months, perhaps foreshadowing a transition from El Niño, to La Niña conditions.

The blue area in the center of the image depicts the recent appearance of cold water hugging the equator, which the satellite measures as a region of lower-than-normal sea level. (Water contracts slightly when it cools and expands when it warms.) Remnants of the El Niño warm water pool, shown here in red and yellow, still linger in pockets to the north and south of the equator in the center of the image.

The image shows sea surface height relative to normal ocean conditions for this time of year. Red (warmer) areas are about 10 centimeters (4 inches) above normal. Green areas indicate near-normal conditions. Purple (cooler) areas are 14 to 18 centimeters (6 to 7 inches) below normal. Blue areas are 5 to 13 centimeters (2 to 5 inches) below normal

“The central equatorial Pacific Ocean could stay colder than normal into summer and beyond. That’s because sea level is already about 10 centimeters (4 inches) below normal, creating a significant deficit of the heat stored in the upper ocean,” said NASA/JPL oceanographer and climatologist Bill Patzert. “The next few months will reveal if the current cooling trend will eventually evolve into a long-lasting La Niña situation.”

A La Niña is essentially the opposite of an El Niño. During a La Niña, easterly trade winds in the western equatorial Pacific are stronger than normal, and the cold water that is normally located only along the coast of South America extends all the way to the central equatorial Pacific. La Niñas change global weather patterns; they are associated with less moisture in the air, resulting in less rain along the coasts of North and South America. They also tend to increase the formation of tropical storms in the Atlantic.

“For the American Southwest, La Niñas usually bring a dry winter, not good news for a region that has experienced normal rain and snowpack only once in the past five winters,” said Patzert.

Assam flood situation worsens

The flood situation in Assam today deteriorated further with the water level of the Brahmaputra and its tributaries rising alarmingly and inundating fresh tracts of land. The worst affected districts are Lakhimpur and Jorhat in Upper Assam and the situation was turning worse in several other districts, officials said.

More than 70 villages have been inundated in Lakhimpur by the rising waters of Ranganadi, Dikroi, Kakoi and Singra, all tributaries of the Brahmpautra. In Jorhat district, Brahmaputra's tributary Saraikoni river has breached two embankments under Titabor sub-division inundating 40 villages. The other affected districts are Tinsukia, Dibrugarh, Dhemaji and Morig
Cherrapunji records 34 cm ending 8.30am on 27.06.2010. Its in the verge of crossing 800 cm for the year. It has received 788 cm for the year. The next in the list is Passighat way down with 239 cm for the year.

Sudden downpour throws Chennai traffic out of gear

CHENNAI: The city experienced a sudden downpour on Saturday afternoon leaving hundreds , including office-goers, stranded at bus stops and railway platforms. Several roads and subways were inundated and traffic was thrown out of gear. Meteorology Department officials said the observatory in Nungambakkam recorded 30 mm of rain during the 12 hours ending 8.30 p.m. on Saturday. The Meenambakkam observatory registered 38.7 mm during the same period. Weather officials said the heat during the daytime helped the development of thunder cloud activity.

According to S.R. Ramanan, Director of Area Cyclone Warning Centre, Regional Meteorological Centre, Chennai has been experiencing unstable weather due to a combination of factors. The development of convective clouds generated in the evening, after intense heat in the day, causes rain, he said. The city has also been experiencing rain due to local thunderstorm activity. This weather is expected to be like this till the end of this month.

Deputy Director-General of Meteorology Department Y.E.A. Raj said it was not unusual to have thundershowers in the evenings during southwest monsoon. “This year, we have had more rain compared to previous years. The rainfall occurs two to three hours after sea breeze sets in as it brings more moisture to the coast,” he said. The sun has been playing hide and seek with the clouds for the past few weeks. This month, so far, the City and Airport has received 84 mm and 117 mm of rainfall respectively, which is much more than the average in June
