An iceberg which is estimated to be around the size of Manhattan or Singapore could threaten shipping if it drifts into busy international lanes.

UK researchers have now been given an emergency grant to track the iceberg which is approximately 270 square miles in size.

The giant block of ice broke away from the Pine Island Glacier in July but it was iced-in due to the freezing winter temperatures in Antarctica.

While the iceberg could move eastwards along the Antarctic coast, it could also drift into the South Atlantic Ocean where it could potentially pose a hazard to ships if it crosses into international shipping lanes

Now the £50,000 research grant will fund a six month project which will predict the movements of the iceberg through the Southern Ocean.

NOAA images show wind farms distort weather radar data, affecting their primary mission of forecasting and safety

"Chaotic wind velocities associated with the rotating turbine blades triggers the doppler radar mesocyclone detection algorithm"

Note: this essay was written by the National Weather Service Forecast Office in Burlington, Vermont and tipped to me by a reader. Vermont's wind farm acreage pales in comparison to places like the Texas and Oklahoma, where there are literally thousands of acres of wind farms right in the middle of tornado alley. I've been there and seen them firsthand.

Certified Consulting Meteorologist Mike Smith writes:

"While driving to Norman, OK recently I saw the newest "wind farm" to the west of Interstate 35 southwest of Tonkawa. Wind farms show up as bright ground clutter on weather radars and here it is."
One has to wonder just how much trouble wind farms are causing the nation's doppler radar warning system. It looks like a classic case of the law of unintended consequences at work. - Anthony



National Weather Service WSR-88D Radar and Wind Farm Impacts


Introduction

The most valuable tool used by the National Weather Service (NWS) to detect precipitation is the radar. Radar stands for Radio, Detection, and Ranging, and has been used to detect precipitation since the 1940′s, with most of the technology coming from the military.

Record snowfall blankets Havre, Montana

What the winter will bring is still unclear

A second snowstorm hit north-central Montana over the weekend, bringing enough white stuff to tie a National Weather Service record for Havre on Nov. 10 set at 4 inches in 1916 and bringing some slippery driving conditions to the area.

Once again, the winter conditions are not expected to last, with temperatures expected to be in the 20s to 30s, depending on the forecaster, today and back into the 40s or even 50s later in the week.

The forecast calls for mostly sunny skies through the weekends with temperatures expected to drop some by Saturday or Sunday.

The long-range forecast still is up in the air, with The Farmers' Almanac predicting the region including Montana will be piercingly cold with about-normal snowfall, while the Old Farmers' Almanac predicts colder-than-normal winter temperatures here, with lower-than-normal precipitation and snowfall.

Preparation for the coming storm

Our current collective condition has never been more precarious - at least not in our lifetime. Worldwide economic collapse seems certain, only the timing and severity can be debated. The planet seems to be convulsing through all kinds of changes, from weather extremes to increased earthquake/volcanic activity, to mass animal die-offs, to greatly increased bolide/fireball events.

Recent US fireball reports (including sound and fragmentation)
Some of these changes are reflected in changes we can see occurring on other planets in our solar system, and may be related to the bizarre behavior of our sun and/or the nature of space around our solar system. Respected meteorologists and atmospheric scientists are warning of an impending ice age - the beginning of which could occur rapidly and with little warning. Secondary concerns have been widely expressed regarding worldwide food supply, not to mention rising prices and environmental instability.

The point here is not to stimulate panic. The point is to focus on what we can do as individuals and groups to prepare a living environment that is mindful of potential threats - an environment we can create with the means at our disposal. Just thinking and planning around this is preparation itself.

German scientists: Solar cycle 24 points to Dalton or Maunder-like minimum, boding ill for a climate cooling

In October 2013 there was a considerable rise in solar activity as the sunspot number (SSN) climbed to 85.6. That's 77% of the mean value reached at this time into a solar cycle since 1750. The following diagram shows the current situation:

SSN versus months since the start of the cycle.
October 2013 deviates significantly from solar cycle number 5.

However we continue to believe that SC 24 will be similar to SC 5. Just how large the uncertainties of the correct description of the 5th cycle is shown by a recently published paper by Rainer Arlt of the Leibniz Institute Potsdam and Ilya Usoskin of the Finnish University of Oulo, who after examining the solar cycles between 1750 und 1850 reached the conclusion that the sunspot count should be lowered by 20%. SC 24 shown by the blue curve is, however, still very much below average, let alone well below the large cycles of the solar maximums from 1940 - 1990.

Spokane International Airport received 1.9 inches of snow Tuesday, according to the National Weather Service. The total was enough to snap a 66-year-old daily record by the slimmest of margins.

Before Tuesday, the most snow Spokane had officially received on Nov. 5 was 1.8 inches in 1947, according to National Weather Service records. The snowfall, which was timed perfectly to make the morning commute miserable for many motorists, tapered off around 2 p.m.

Forecasters expect temperatures to remain high enough to keep flakes away for the rest of the week, though chances for rain remain through Sunday. Showers on Thursday could grow heavy at times, with between a quarter- to half-inch of rain expected throughout the day.

Temperatures through Sunday should be in the mid- to upper-40s for highs and near freezing at night, forecasters say.

SIOUX FALLS, S.D. (AP) -- weather system that crossed southern South Dakota set snowfall records in Rapid City and Sioux Falls. The National Weather Service says 3.1 inches of snow fell at the Rapid City airport on Tuesday, breaking the 2008 record for the date of 1 inch.

Sioux Falls got 5.7 inches of snow, breaking that city's record for the date of 1.5 inches set in 1959. Some parts of southern South Dakota got even higher amounts of snow, but it was expected to start melting on Wednesday.

The weather service forecast called for high temperatures from the mid-30s to the mid-40s.

Snowfall at Rohtang Pass, Himachal Pradesh
Rohtang Pass is under over 100cm (39 inches) of fresh snow, making it difficult for the Border Roads Organization (BRO) to clear the highway.

Higher reaches of Dharamshala, Shimla, Kinnaur and Chamba also received heavy snowfall in the last 48 hours.

Most popular tourist places in Himachal Pradesh received two feet thick snowfall on Thursday, reported India TV.

At present, even pedestrians are not being allowed to cross Rohtang (13,050 feet) where high velocity cold winds and blizzards may kill people. Eight people were killed in a similar attempt to cross Rohtang in November 2009.

A resident of Keylong, Kumari Anita, said, "We had come to Kullu to buy rations and woollens before the closure of Rohtang Pass for the next six months. But the sudden snowfall has forced us to take shelter at a relative's house. We have a jeep full of essential commodities which we need to take home soon after opening of the road."

From record wildfires to extreme cold inside two weeks: Australia experiences coldest November night in 40 years

Image

This was the scene outside Canberra a couple of weeks ago... since then Australia has gone deeper into Summer and temperatures have plunged to freezing.
Parts of southern New South Wales and the Australian Capital Territory endured their coldest November night in over forty years, with the region set to chill again tonight.

The ACT saw some of the coldest temperatures, with Canberra Airport dipping to -1.5 degrees, its coldest November night since 1970. Tuggeranong fell to a chilly 1.2 degrees, its coldest November night in a decade.

In NSW, Goulburn Airport dipped to -3.1 degrees and Thredbo -6.1 degrees, the coldest November night since 2006.

The unseasonably cold night was caused by a variety of factors. Firstly, a gusty cold front moved across the region yesterday, leaving behind a pool of cold air. Overnight, a high pressure system moved in, causing winds to ease as well as clear skies, allowing the mercury to plummet.

This high will continue to bring similar conditions tonight, allowing for the region to shiver through another cold night.

Canberra is expected to see it dip to zero tonight, and if this occurs, will be the coldest pair of November nights on record. Thredbo is expected to reach minus five, which would be its coldest pair of November nights since 2006.
