La Niña on Forecast, Oh, also a Word on Readiness

June 5th, 2010   by Walt 

The Climate Prediction Center has determined that El Niño dissipated during May, so we are looking at cooler Pacific waters now. This could be the beginnings of a La Niña which could mean the Atlantic hurricane season could be more severe.

Whichever way the hurricane season turns out, spring and summer are times of high risk for severe storms. As I post this, NOAA‘s NWS has severe thunderstorm warnings out for several states and several tornado warnings active, so hurricanes are not the only reason people should stay prepared.

For flashlights, I recommend the new LED style lights. They are so much easier on batteries, and the LEDs don’t burn out like the older incandescent bulbs. They come in varieties from similar to “regular” flashlights to lanterns to light entire rooms. I also recommend getting the ones that take regular flashlight type batteries (AAA, AA, C, or D). Remember that you will need electricity to recharge rechargeable batteries (duh) so for long term use, replaceable batteries are the best. The rechargeable ones are OK if the power is out for a few to several hours, but you will be running out of power after a few days if you cannot recharge the batteries.

Don’t forget battery operated radios (with fresh and replacement batteries) as well as fresh water and food that stores well for long periods of time and does not require cooking (be sure the food is something you can open without electricity!).

If you live in a mobile home, a low spot, or any other high risk area, be prepared to leave right away if told to do so.

Follow directions about staying away from windows and finding a safe place to stay while severe weather is nearby.

Here is the link from the NWS site to get your information about what you need and what to do. Following the directions could save your life or the life of a loved one.

Understanding Doppler RADAR – NWS Style

April 25th, 2010   by Walt 

While on the subject of weather technology, here is a link to an easy online course by The National Weather Service about their WSR-88D Doppler RADAR system.

It is informative, yet easy to understand. It covers the basics of how they use Doppler for weather purposes.

There is an easy quiz at the end if you wish to take to receive a certificate of completion. If you are not interested in the certificate, at least you will understand what the colors mean and just what the whole picture is telling you.

If you wish, here is a boiled down version minus the questions and certificate.

Oh, and have fun!!

Weather Satellites: Happy 50th Birthday!!

April 25th, 2010   by Walt 

This is a bit late, but it was “only” 50 years ago on April 1 that the first weather satellite was launched. TIROS-1 (Television Infrared Observation Satellite) sent its first fuzzy picture back from orbit.

“This satellite forever changed weather forecasting,” said Jane Lubchenco, Ph.D., under secretary of commerce for oceans and atmosphere and NOAA administrator. “Since TIROS-1, meteorologists have far greater information about severe weather and can issue more accurate forecasts and warnings that save lives and protect property.”

Here is the article from the National Weather Service that includes a short history of their “birds” above helping keep tabs on the weather.

Again, “Happy birthday!”
