Meteorology — Observations


Just the other day, a friend and I were discussing the astounding amount of information that is available o'er ye olde Internet.



The weather forecast above is quite specific ( down to precipitation, humidity, wind speed, wind direction and cloud cover BY THE HOUR ); whether it'll prove accurate is another matter.


It amazes me that while sitting at my desk I can take a look at the water flowing in a stream that's just a bit up the valley from me and I can call up a national precipitation map:



Back in February, I posted a national map showing snow cover on the day that 49 of the 50 states had some snow on the ground ( the only exception was Hawai'i— and that was unusual because Hawai'i usually has snow on the top of Mauna Loa ).

La Nina Event May Strengthen, Australian Bureau Says

By Wendy Pugh

Aug. 4 (Bloomberg) -- A La Nina weather event, which can bring above-average rainfall to Australia and parts of Asia and drier conditions to the southern U.S., is in its early stages and likely to strengthen, according to Australia’s forecaster.

Indicators including ocean temperatures and trade winds have reached or exceeded La Nina levels, the Melbourne-based Bureau of Meteorology said on its website today. Computer models predicted the central Pacific would continue to cool in coming months, indicating La Nina would strengthen, it said.

La Nina can disrupt agricultural output in Asia, and may cause flooding in rice-growing regions of the Philippines later this year, the weather agency in the world’s biggest buyer said last month. The phenomenon can also parch the southern U.S. and intensify hurricane development in the Atlantic Ocean.

“North America and the western Pacific are the two areas that see the greatest effects from a La Nina,” Mike Pigott, a meteorologist with Accuweather Inc. in State College, Pennsylvania, said by phone. “As things continue to develop you are likely to see more effects from this.”

Australia’s Murray-Darling Basin, which produces more than a third of the nation’s food and is recovering from drought, had its wettest July since 1986, the Bureau of Meteorology said yesterday. The developing La Nina may bring further rainfall, based on typical patterns linked with the event for winter and spring, Melbourne-based climatologist Lynette Bettio said.

Increased Rainfall
“There are chances of increased or above-average rainfall in eastern Australia in the coming months,” she said yesterday. Winter in Australia, the fourth-largest wheat exporter, is from June to August. Crops require spring rain ahead of harvesting.

The developing La Nina, which can also affect the Indian monsoon, was unlikely to have driven the heat wave in Russia or flooding in Pakistan, Bettio said.

“It’s mostly concentrated in the countries around the Pacific Basin,” she said. “It sets up atmospheric patterns that translate across the equatorial region, so we do see some translation into the Indian Ocean and into the Atlantic Ocean.”

Russia’s worst drought in at least 50 years has cut grain production and now threatens sowing plans for winter crops, the country’s national weather center said yesterday.

Farm production in Pakistan may drop 10 percent to 15 percent because of damage caused by floods, Nasir Cheema, president of the agriculture chamber of commerce, said Aug. 2. China’s worst flooding in more than a decade may cut production of rice and cotton, analysts including Li Qiang, managing director at Shanghai JC Intelligence Co., said this week.

Wildfire Threat
La Nina is a cooling of the equatorial Pacific Ocean occurring on average every three to five years and lasting nine to 12 months, according to the U.S. National Oceanic and Atmospheric Administration. Some events have lasted as long as two years.

The event often brings drier, warmer weather to the southern half of the U.S., increasing wildfire threats in Florida and California. Florida is the second-largest producer of oranges, behind Brazil.

Increased rains in southern Africa, northeastern South America and the U.S. Pacific Northwest are also common during La Ninas, according to NOAA.

This shows the most recent image of the United States, taken from a NOAA satellite. This image is taken in the infrared band of light and show relative warmth of objects. Colder objects are brighter and warmer objects are darker. Lower layers of clouds, generally warmer and lower in altitude, are colored gray. Colder and generally higher clouds tops are highlighted in colors. IR imagery is useful for determining cloud features both at day and night.

By now, you've heard of them. Haarp projects are microwaving ionosphere. It heats up hydrogen molecules. It makes hole in the Ozon layer.

It causes global warming.


Get it?


Take a deep breath.
