Studying the JET STREAM has long been an indicator of the weather to come, and to study the jet stream attention must turn to the SUN.
When solar activity is HIGH, the jet stream is tight and stable and follows somewhat of a straight path. But when solar activity is LOW, that meandering band of air flowing 6 miles above our heads becomes weak and wavy, it effectively buckles which diverts frigid Polar air to atypically low latitudes and replaces it with warmer tropical air.
