World weather remains disturbed, with powerful snowstorms enveloping parts of the United States and Russia, flooding in Malawi and Mozambique and a wet winter storm pounding the US west coast. The flooding along the Zambezi in Africa appears to be part of a larger emerging weather pattern that may disrupt the area in the same way that the lengthening monsoon season has been causing persistent flooding in Southeast Asia.

What has developed into a strong northeaster over the eastern seaboard of the US began with an unusual confluence of fronts, including a Canadian low that moved east to west for a period of time. This is a most unusual event, as prevailing winds blow from west to east.

There is also evidence of disruption of the flow of the Pacific trade winds that normally circulate around the equator, with unusual north-south movement taking place instead.

Very powerful snowstorms have enveloped parts of Russian Siberia, causing an entire town to be buried in 50 centimeters of snow, and isolating Sakhalin Island for a period of time yesterday.

The US east coast storm is currently still in progress and is expected to dump as much as 36 inches of snow on parts of New England. The storm has not been as heavy as expected farther south, but its rotation may yet bring substantial snow to the New York City area.

According to the Free University of Berlin’s Stratalert service, stratosphere over the northern hemisphere continuesunusually warm, meaning that unstable weather is likely to continue into the spring.
