Crisis Ensued The Final Time Earth’s Magnetic Poles Flipped, Researchers Say : Npr
For instance, track 140 lasted various days, migrating north from the Bering Sea, but the typical SIC anomaly (within a 600-km radius) is only calculated for the 27 h within the period of interest. The sum of these anomalies yields the accumulated SIC anomaly (∑SICa). Other measures of storm intensity are also summarized, and this process is repeated for every of thousands of cyclone tracks. At some point in recent weeks, a once-in-a-lifetime event happened for folks at Greenwich in…
