Winters on the U.S. East Coast are ordinarily moderated by the Bermuda high, a swirling mass of moist tropical air off the Atlantic Coast that acts as a protective buffer to icy arctic blasts. This winter, because of abnormal patterns in the high altitude winds (TIME, Jan. 20), the Bermuda high has been flubbing its job. Result: successive masses of polar air have flowed down the Mississippi Valley and eastward, spreading out to reach deep into Florida, to bring abnormal cold and, in the clash with tropical air masses, heavy rains and snows...
...itself off from a freeze and a light snow-which, among other things, broke up a Mardi Gras parade in New Orleans and drove vacationing President Eisenhower indoors at Thomasville, Ga.-when a violent new storm boiled up off the Louisiana coast. Mixing its Gulf moisture with the cold arctic air, it swept north and east, dumping the season's heaviest snowfall from Jackson, Miss, on up into Maine. Temperatures sank to a bitter subfreezing all along the path, sank lower in its wake...
Southerly Swing. Unlike the Russian Sputniks, which sweep close to the Arctic and Antarctic Circles, the Explorer follows a sinuous orbit around the earth's middle, crossing the equator at an angle of about 34° and coming only as far north as Atlanta. At its highest point (apogee), the orbit rises to 1,700 miles above the earth, descending to about 200 miles (perigee). The round trip takes 114 minutes. This is a "safe" orbit, above nearly all the drag of the atmosphere, and higher than the orbits of the Russian satellites...
...news to the World Warning Agency near Washington, D.C., and a volley of messages alerted scientists all over the world, including those parts that were still in darkness. The effects of the flare, a violent magnetic storm and a radio blackout, were observed from the South Pole to the Arctic and all around the equator...
...Weathermen are getting the first really worldwide picture of the atmosphere's circulation. U.S. Weather Bureau scientists drifting on the Arctic ice keep track of winds and pressure changes that will affect the weather of Keokuk and Odessa. Their colleagues at the South Pole do the same for the Antarctic. Already their reports have improved weather forecasting for the Southern Hemisphere...
