WEATHER forecasting relies on more than the simple observation of the sky. Its methods range from weather folktale simplicity to elaborate computer simulations. Sometimes, people depend on weather forecasts through such methods as watching the groundhog. If the groundhog sees its shadow, it is predicted that there will be six more weeks of cold or winter, but this is not, of course, the most scientific way. In ancient China, a clear sky with light winds meant low overnight temperatures. Aristotle knew about red skies in the morning and the meaning of haloes around the sun or moon. These meant a falling barometer and a backing wind which could be precursors of bad weather.
But to really forecast the weather, one needs to look at things like wind speed, direction, temperature, air pressure, precipitation, and humidity. There are different ways and devices to measure these things. These include the thermometer, anemometer, the weather vane, and the Beaufort scale.
A geologist, Dr. Carlo Primo David, and three computer engineering graduates from Don Bosco College have created a personal weather bureau, a data collection device capable of delivering up-tothe minute information on the weather directly to cellphones. The group which is working with the University of the Philippines National Institute of Geological Sciences will soon introduce an Automated Monitoring System (AMS) which offers a cost-effective alternative to the weather monitoring stations currently being used by the PAGASA.
The AMS has become a candidate for the best research and development project to be awarded by the Department of Science and Technology and the Philippine Council for Industry and Energy Research Development.
The AMS could be an important part of the country’s disaster preparedness program. At the very least, it can help prepare us to know and dress for the weather even before we leave our homes.
