When Is A Tropical Cyclone A Tropical Cyclone?

Seems logical enough doesn’t it, a tropical cyclone is a tropical cyclone. Reality is a tropical cyclone is a tropical cyclone only when ‘someone’ decides it is a tropical cyclone. You are probably thinking so what, no real big difference there, but in a science primarily governed mathematical equations and the laws of physics and [...]

Does Size Matter?

By Angela Fritz When you want to determine how intense or how strong a hurricane season was, there are many ways you can calculate it.  An obvious place to start would be summing the intensity of the individual tropical cyclones in that season.  When a cyclone is defined as a tropical storm or a hurricane [...]

What Happens When You Put Thousands Of Weather Geeks In A Building?

Have you ever wondered what happens to your brain after spending all day for four days listening to presentations that last for 15 minutes each and are given by different speakers from all over the world?  Well, for me I usually come to the end of that four days with more questions than answers, but [...]

What Is a 100 Year Flood?

Having witnessed firsthand the devastation of a river flood this past month, it seemed an appropriate time to look into an area of science that can sometimes be very confusing – probability of prediction and its fluid nature.  In this case we will focus on what a 100 year flood translates into, but another common [...]

Are Seasonal Tropical Cyclone Predictions Useful?

This time a year, those involved with forecasting tropical storms and hurricanes in the Atlantic Ocean tend to get busy.  On June 1st we kicked off the official start of the 2009 hurricane season for the Atlantic, and while we have not had any name storms yet there was already a close call (Tropical Depression [...]

Does Sea Ice Really Matter?

Some of you who follow climate topics may have seen some articles in recent months talking about Sea Ice.  Some of the chatter has been about whether Sea Ice levels have really changed over the last 30 years.  Others have looked at the changing sea ice patterns in the Arctic Ocean and discussed the possibility [...]

Data is Data, Right?

In considering the topic of ‘climate forecast uncertainty’ it became clear that one could easily write a whole PhD thesis on the topic and if I don’t want to read that I am sure you don’t either.  At the same time there was no way to scrunch it down to one single post.  So this [...]

Water Vapor – A Nicer Greenhouse Gas?

In a follow up to the last post on viable renewable energies, I had some questions as it relates to ‘water vapor’ and the role it plays with climate.  What many people do not know is that water vapor is actually the most abundant greenhouse gas.  Here are a few links to educate yourself a [...]

Viable and Renewable Energy – Possible?

We hear a great deal of talk today about ‘Renewable Energy’, sometimes in conjunction with climate change and environmental implications and also in the context of the fact that our primary sources of energy today are not endless. It is expected that global energy demand will double between 2005 and 2030. At the same time [...]
