Essay: The new days to come; stagnant weather systems

Living North of 30 degrees latitude? If so, you may have a sense that the weather has changed, then look at the equator to get inspired about what is happening with the climate. As always, the weather near the equator is far more predictable and repeatable then further North, of course not counting the occasional Tropical storm Typhoon or Hurricane, daily temperatures rarely vary a great deal. Contrary to places like New York city, Toronto, London , Beijing and Tokyo, where day to day weather was once upon a time more inconsistent, variable at times unpredictable even with the best means of prediction. But you may have noticed that the weather has changed . Why? Because extremes in temperature mixing between massive cold and warm air masses is waning. This has immediate impacts, such as I gather with news from well informed equatorial sources, explaining the disappearance of subtle summer seasons, the grasp of Polar Air can go that far, albeit indirectly.

Consider the North Pole region as a powerful source of cold air even during summer, it moderates overheating Air Masses further South, but it plays larger role, it is a clasher, creating constant conflict with warmer air… Warming up Polar air reduces the temperature contrasts or lowers air mass density differences, the very reason for air mass clashing, then everything else South slows down, like at the equators doldrums. This is what is happening on a worldwide scale. Current over all impact of Global Warming is more predictable slow moving sometimes nearly stagnant weather systems.

This lack of weather variances, or daily change, can be devastating in many ways, not the least Psychological, in one zone of the world, where a High pressure system languishes at one spot for several days, the sun usually warms everything up quite rapidly. As a recent example, Northern Arctic Quebec Canada, during May of 2005, with thousands of lakes still frozen, temperatures were at an astonishing 30 degrees C. The opposite happened during the same time period, with a Low pressure system vacillating to the South of Newfoundland giving some dreary wet and cool weather, cooling the Northeast Coast of the US and Canada with daily highs 20 degrees cooler then weather more than 1000 miles to the North.

Climate Change means dramatic transformations, compared to past temperate zone weather. These may be beneficial for some winter weary warm air loving Northerners, but can be a nightmare just as much. And this is only the beginning of a new worldwide weather order. WD June 13,2005
