When a moderately
strong bolt of cyber lightning struck the virtual rock, it created
pressure waves that peaked at about 70,000 atmospheres, well into the range needed to produce shocked quartz, the researchers report this month in Geophysical Research Letters.
As the jet produces these
pressure waves and propagates ahead of them, the regions of lower
pressure are usually
strongest behind the nose of the jet, on the wings and body.
A blocking high
pressure system in the North Atlantic creating consistent
strong northeasterly flow would provide
wave action that may have contributed to the chevron ridge formation in the Bahamas and Bermuda.
Huge
waves have battered the coastline where storm surges created by a series of deep low
pressure systems and
strong winds blowing over thousands of kilometres combined with high tides.
The heat
wave was due primarily to a natural phenomenon called an atmospheric «blocking pattern», in which a
strong high
pressure system developed and remained stationary over western Russian, keeping summer storms and cool air from sweeping through the region and leading to the extreme hot and dry conditions.
The culprit appears to be several
waves of warm high -
pressure ridges that have swept over Greenland, each
stronger than the last, with the most recent one squatting over the island for about a week.
