Mechanism for Linking Solar Activity to Weather-Scale Effects, Climatic Changes and Glaciations in the Northern Hemisphere

Crime and Climate

“…The magnetic pole migrates at about 5-10 km per year. Bucha (1984) illustrates the position of the geomagnetic north pole over the last 18 000 years based on values obtained in Czechoslovakia, Japan, and the United States, its trajectory appearing to follow a quasi-ovoid form over the period of historical measurements, with a four-leafed clover form in its longer records.…”

“…Bucha (1984) believes that during brief but highly energetic solar flares the site of the magnetic pole and its associated auroral oval favors the development of low-pressure systems and storminess, which in turn helps to maintain milder temperatures, and that this condition applied to the North Pacific-Aleutian area during the late Pleistocene (18 000-12 000 BP) This would explain the lack of ice sheets in eastern Siberia and Alaska at the time. In contrast, according to Bucha, the remoteness of the North Atlantic region from the north magnetic polar area during the last glaciation maximum permitted a stable high-pressure situation favoring meridional air flow and the build-up of major continental ice sheets in eastern North America and northwestern Europe.…”

“…Such events trigger displacements of the jet stream and related atmospheric systems throughout the high-and mid-latitude belt of the northern hemisphere (Bucha, 1984).…”
