  • On May 18, 1980  Mount St. Helens erupted in a cataclysmic event that reshaped parts of the Cascades Mountains to the southwest of Seattle.  Since the eruption went mainly sidewise as the north side of the mountain collapsed, the eruption had limited climatological effects globally, although the ash did cause cooling and surface problems in…

Now that NOAA has predicted that…

  • As we’ve discussed in earlier posts, an El Nino is currently present in the equatorial Pacific Ocean.  This means that the surface water temperature there is above normal.  One of the consequences of this is that more strong hurricanes form than usual, since the warm water acts as fuel for the storms. This year, the…

  • Climate data sources: AgroClimate

    AgroClimate is a web site developed by scientists associated with the Southeast Climate Consortium.  It contains climatological information for stations around the Southeast based on NWS cooperative observers as well as some mesonetworks like Florida’s FAWN.  I’ll talk more about mesonetworks next week. One of the most useful things about AgroClimate is its ability to…

  • If you are a meteorologist, a bright sunny day with low humidity is dull and boring.  Photographers know it’s hard to take good photographs in harsh sunlight, so sunshine is not welcome to them either.  Rain, snow, fog and severe weather all bring their own special charms. The Digital Photography School posted an article today…
