13 November – LA NINA BRINGS COLDER WINTER FOR NORTH INDIA

weather phenomenon that typically delivers harsher winters is on the way and expected to add to Asia’s energy crisis.

The La Nina pattern, which forms when equatorial trade winds strengthen to bring colder, deep water up from the bottom of the sea, has emerged in the Pacific. That typically spells below-normal temperatures in the northern hemisphere and has prompted regional weather agencies to issue warnings about a frigid winter.

Several nations and particularly China, the top energy consumer, are grappling with surging fuel prices and for some, power shortages or curbs on supply to heavy industry. Coal and gas prices are already elevated and a bitter winter will add heating demand that’ll likely spur further gains.

Temperatures are expected to be colder than normal this winter across northeastern Asia. Weather forecast data is a critical component of predicting how much energy load will be required.

India

? Temperatures in India are expected to fall to as low as 3 degrees Celsius (37 Fahrenheit) in some northern areas in January and February before recovering. Unlike in other nations, cooler weather typically leads to lower energy consumption as demand for air conditioning wanes.
? Most importantly, the nation is anticipating a drier period after the end of the monsoon season. Key coal mining regions suffered flooding in recent months that triggered a squeeze on supply of the fuel used to produce about 70% of the nation’s electricity.
? Aside from La Nina events, there are other factors that can impact the region’s winter weather. Climate change has led to a lack of sea ice in the Arctic’s Kara Sea, which may be contributing to high pressure ridging in that area. This leads to downstream colder conditions across northeast Asia, “like what happened last winter.
? There are also indications the polar vortex a girdle of winds that bottle up cold at the pole could be weaker than normal at the start of winter, which would allow frigid air to spill south .
