Pat Shingleton: "In Line With Storms"

In the middle of the eighteenth century, seafarers believed a major storm would occur around the end of summer, closer to the autumnal equinox. As noted in a previous column, sailors would refer to these systems in September and October as a "line storm." When the sun crossed the equator, its rays would also move in a line across the equator. The Sun's rays caused thermal contrasts. Cool air from the north colliding with superwarm southerly air activated more tropical storms. The results are contrasting air masses that produce drastic fronts and winter-type storms in temperate regions. The traditional period for peak storm threat activity is the 60-day interval around Sept.10. The Caribbean and New England become active and vulnerable.
