PAG-ASA Weather station In Baguio

On our first plant visit, we went to PAGASA. We were introduced to the equipment used to measure atmospheric pressure, wind and wind velocity, amount of rainfall and relative humidity. A reading is done in a 3 hour interval or 1 hour interval is there is a possible typhoon coming towards the country. The data is sent to the central office for analysis and used for forecasting the weather.

The person in-charge showed us the chart from the microbarograph that indicates that a typhoon is coming. We saw a V-shaped graph which means that there is a drop in atmospheric pressure when a typhoon is coming and goes back to its normal reading when it already far from the country.

With that highly sensitive device, we can directly observe that a possible typhoon is coming.
