Have There Been More Hurricanes In Recent Years Because of Technology?

     Have there been more hurricanes in recent years? Is that from climate change? Or is it just an advancement of technology? The National Hurricane Center's Christopher W. Landsea, Chief of the Tropical Analysis and Forecast Branch, and Eric Blake, a Senior Hurricane Specialist, studied this topic in a recent article of theirs. About 15 years ago, scientists and researchers found that the number of hurricanes had increased over the past hundred years. But interestingly, during the 1940s and 1950s, there was an increase in short-lived or low-impact storms. At the same time, there were more aircraft over the oceans and the Hurricane Hunters began missions looking for hurricanes.  Last year, nearly 42 trillion dollars of damage were caused by tropical cyclones. This included a record-breaking 13 in the U.S., six of which were in Louisiana. Down in Central America, trillions of dollars in damage was delivered by destructive hurricanes such as Hurricane Iota .  O...

Part 1: Atmospheric Setup Supports Wintry January

The atmospheric setup that is taking place is indicative of a wintry January.

First is the North Atlantic Oscillation. Basically, it measures whether it will be warm or cold. This NAO, when positive, usually means warmth and negative usually means cold. 
The same goes for the Atlantic Oscillation.

The setup happening is where high pressure gets set in up north, near Greenland. This is called the Greenland Block. 

When this happens, and low pressure systems ride in the southern US, it often leads to wintry precipitation.

A third thing is that the polar vortex, which became a popular term a few years ago, is likely to split up.

This effectively sends colder air farther south, and can make storms stronger in our area. 

All in all, there are several signs pointing to a wintry January. 

But it is Baltimore, and things can change or be just barely on the wrong side.
