India cold wave: Delhi reels from coldest day in more than a century

India cold wave: Delhi reels from coldest day in more than a century. By the BBC.

Just a quick sample of what you’re not hearing in the News. The last few northern winters have seen a rash of cold records set across the northern hemisphere. Australia had its coldest ever December day about a month ago. The media nearly always ignores the cold records, but dwells on the warm records.

India’s capital Delhi has recorded its chilliest day in more than a century amid a severe cold wave across the northern part of the country. …

It was the coldest day in Delhi since records began in 1901. The previous low was 9.8C on 2 January 2013, according to meteorological officials. …

Unlike in European and US cities, where most buildings are equipped with central heating, homes in some of India’s coldest cities are not built for chilly winters.

What’s happening? The Sun has gone quiet, as predicted several years ago. What we speculated would happen is that solar influences would cause the jet streams to loop more north and south, rather than east west. (This is based on the solar-earth relationship for the last few millennia continuing its pattern.) This has come to pass.

For the last few decades:

Now:

That increased north-south loopiness of the jet streams means that polar weather is often blown into the mid equatorial regions, such as Australia and North America. It also seems to bring in hot blasts from nearer the equator. As a result, the last three years or so has seen increasing weather variability in the mid-latitudes, with hot and cold blasts.

We further speculated that the increased friction of jet streams rushing by one another would cause extra clouds, which would cool the planet. The global temperature peaked in early 2016 in a big El Nino and is down almost half a degree since then (compared to global warming since 1900 of about 0.9C). Let’s see what happens next.
