El Nino now seen more likely to last into spring

Posted by Flaman Agriculture Aug 14, 2015

Reuters is reporting that  . . .

A U.S. government weather forecaster on Thursday raised the likelihood that El Nino conditions would last into the Northern Hemisphere’s early spring to 85 per cent, boosting the probability that drought-stricken California could see increased rains.

The Climate Prediction Center, a U.S. National Weather Service agency, last month forecast an 80 per cent chance that conditions would last through early spring. The CPC still says there is a more than 90 per cent chance that El Nino conditions would last through the Northern Hemisphere winter.

The new forecast marginally raises the risk that the El Nino phenomenon, the warming of Pacific sea-surface temperatures, will unleash a period of extreme and potentially damaging weather across the globe.

Past instances have caused heavy rains and floods, hitting grain crops in South America, and scorching weather as far as Asia and East Africa.

But one potential El Nino beneficiary could be California, where record-low rainfall has prompted water usage restrictions and contributed to the spread of devastating wildfires.

“It definitely would increase the likelihood of heavy rains in the winter there, which would certainly improve their situation tremendously,” said Donald Keeney, senior agricultural meteorologist with Maryland-based MDA Weather Services.

California could begin to get increased rainfall as early as October and definitely by November or December, Keeney said.

Rainfall will probably not increase in the Pacific Northwest states of Oregon and Washington, which are also suffering from droughts, although they could experience higher temperatures like much of the northern U.S., Keeney said.

The CPC said the effects of El Nino were likely to remain minimal across the contiguous U.S. for the rest of the summer but would increase into the late fall and winter.

In Western and central Canada, an El Nino event is most often associated with above-normal temperatures and drier conditions during winter.

El Nino would probably contribute to a below-normal Atlantic hurricane season, the CPC said. That would reduce the likelihood of storms disrupting energy operations in the Gulf of Mexico.

However, the agency said El Nino was likely to lead to above-normal hurricane seasons in both the central and Eastern Pacific hurricane basins.

Record El Nino makes global record-hot year look inevitable

Posted by Flaman Agriculture Jul 20, 2015

Bloomberg is reporting that . . . .

This is a new kind of heat. In more than 135 years of global temperature data, four of the five hottest months on record all happened in 2015: February, March, May, and now June. 

This has been the hottest start to a year by far, according to data released today by the National Oceanic and Atmospheric Administration. The record heat is likely to continue as an already strong El Niño weather pattern in the Pacific Ocean continues to intensify, ripping more heat into the atmosphere. This monster El Niño may itself be on track to break records.

Results from the world's top monitoring agencies vary slightly. NOAA and the Japan Meteorological Agency both had June as the hottest month on record. NASA had it as tied with June 1998 for the hottest. All three agencies agree that there has never been a hotter start to the year than the past six months.
