Welcome to the

issue of the WEATHERFUN Newsletter


Words From Jerry
Welcome fellow Weatherfun members to the Sept issue of the Weatherfun newsletter and Jerry's words.

I will be short tonight because I forgot what the date was and I am behind.

As far as Earl goes it was not that much of a bad storm in my area. If you read my wrap up you will see I only received 0.72 of an inch of rain, and although my flag has not been moving that much the wind seems to be picking up at this hour.

I hope everyone is enjoying the end of the summer. It has been very hot here in Warren and we have had to sleep with the AC just about every night due to the high heat.

2011 WEATHERFUN REUNION: Please note that next summer's reunion will be one week later. Some members have former events to attend and they do not want to miss our reunion. So, we will go one week later.

It will be a reunion that you will never forget. I will be working with some members on an event that I know you all will enjoy very much. I will be a reunion that you will not forget for a very long time. I will need a driver this year because I now have an electric wheel chair and will need a way to get around. It will make it much easier on me so that I can take part in all events. Again please keep this time open for a great event.

Remember that this is your newsletter and if you have a weather related article that you would like to see in this newsletter please send it to Bill or me and we will see when we can get it in.

Till next month enjoy the rest of your summer and get ready for some of the best weather of the year that we can have in the fall.

Did You Know?
What is a microburst?

A microburst is a small, very intense downdraft that descends to the ground resulting in a strong wind divergence. The size of the event is typically less than 4 kilometers across. Microbursts are capable of producing winds of more than 100 mph causing significant damage. The life span of a microburst is around 5-15 minutes.

When rain falls below cloud base or is mixed with dry air, it begins to evaporate and this evaporation process cools the air. The cool air descends and accelerates as it approaches the ground. When the cool air approaches the ground, it spreads out in all directions and this divergence of the wind is the signature of the microburst. In humid climates, microbursts can also generate from heavy precipitation.
