The General Circulation Models (GCM) are weather forecast models that predict general weather patterns for many years out. Some of these models forecast out to 30 to 50 years. The main purpose is to run different variables to see what extent man impacts are on climate (Global Warming or Climate Change). One of the main
Read MoreThe winter of 2013-2014 is not quite over as the forecast models continue to show cold air masses that will continue to move down from the north and impact Midwest and East Coast of the US during the week of 2-24-2014. Just how cold was January 2014? According to this source, there were 4406 cold
Read MoreLenticular cloud formation (like photo above) are photo gems that we love to view. However, if you are in an airplane you probably want to avoid. These clouds can be found quite often in the mountain areas of Western US. They usually form when we have strong westerly winds aloft. The danger is in Rotor
Read MoreAtmospheric rivers (AR) are long and narrow bands of highly-concentrated moisture in association with winter storms and occur throughout the middle latitudes near major oceans. Thus the US West Coast is subject to this. The amount of moisture can be extreme especially when the air is forced up the mountains along the West Coast. How
Read MoreJanuary 6 and 7 of 2014 brought many record cold temperatures (F) and here is a very brief list: Chicago -16, Toledo -14, Cleveland -11, New York City +4, and Pittsburgh -9. Now (1-28 and 1-29) another arctic air mass is sweeping into the Southeast US and snow and ice storms will sweep across much
Read MoreMuch of our weather work is gathering historic weather data for clients and providing detailed analysis. It is certainly interesting looking at historic data and recreating what happened. However we do plenty of operational weather forecasting in United States and also on a worldwide basis. The main focus now is the cold weather experienced so
Read MoreAircraft accidents are less likely to occur today than years ago and this is the case even with the growing number of aircraft in operation. From 1959 to 2008 there were 27,877 onboard fatalities and comparing the same statistic for 1999 to 2008 there were 4717 fatalities. Certainly good news. The Aircraft Crashes Record Office
Read MoreThe cold air that has gripped much of the eastern 2/3’s of the US during the week of January 6, 2014, has the media using the term “the polar vortex.” I have seen the term: “a dive into the polar vortex.” This is certainly is a term that gets everyone’s attention. What is a vortex?
Read MoreThe majority of meteorology goes into weather forecasting current day to 5 days out. There are also 15 day forecasts and even seasonal forecasts. A narrower field of meteorology is the field of forensic analysis which involves looking at past weather data. This is not as exciting as all the popular TV shows such as
Read MoreThe Hurricane season in the US Atlantic goes from June 1 to November 30. The 2013 season was the first since 1994 with no major hurricanes. Also the 2013 season was first since 1968 that did not have at least a category 2 intensity hurricane. Another measure of hurricanes is what is called the Accumulated
