UNUSUAL MARCH FREEZE GRIPS MEXICO

[Mark]

The late-season cold currently engulfing much of the CONUS has also dipped unusually far south.

Remarkable cold for late-March has even swept swathes of Mexico this week. Readings of -15C (5F) have been noted in La Rosilla, for example — lows not too far off the locale’s all-time monthly record.

A weak jet stream is responsible for this southern intrusion of cold air into Mexico’s highlands.

In short, low solar activity impacts Earth’s weather/climate via a number of different mechanisms. The most notable being the reduction of energy entering the jet streams. This reduction changes the jet’s usual strong and straight ZONAL flow to more of a weak and wavy MERIDIONAL one. And this, in turn, and depending on which side of the stream you’re on, means you’re either in for a spell of unseasonably cold or warm weather and/or a period of unusually dry or wet conditions:
