What is PAGASA and how did they predict the weather?
The pressure, temperature, dew point temperature, wind direction and speed are observed at selected levels in the atmosphere using radiosondes which record these data by tracking helium-filled balloons attached to transmitters.
How PAGASA monitors the weather and predict typhoon movement in the Philippines?
PAGASA installed its first Doppler weather radar station in Baler, Aurora and another in Baguio. The new weather radars can monitor the typhoon and its movements, amount of rainfall either moderate or heavy and real-time atmospheric forecasts using a visual radar monitor, an example was that of Typhoon Basyang in 2010.
How does a weather forecaster know the intensity of the typhoon coming to the country?
Forecasters use a variety of observational information from satellites and aircraft to determine the current location and intensity of the storm. This information is used along with computer forecast models to predict the future path and intensity of the storm.
Who monitored the movements of the typhoon?
PAGASA forecasters use three domains where they monitor, analyze and forecast tropical cyclones: the Philippine Area of Responsibility, Tropical Cyclone Advisory Domain and the Tropical Cyclone Information Domain. These domains can be visualized as “three-layered zones” that enclose the country.
What is purpose of Pagasa?
PAGASA is the Philippine national institution dedicated to provide flood and typhoon warnings, public weather forecasts and advisories, meteorological, astronomical, climatological, and other specialized information and services primarily for the protection of life and property and in support of economic, productivity …
Why it is important track the pathway of a typhoon?
Using a consensus of forecast models, as well as ensemble members of the various models, can help reduce forecast error. An accurate track forecast is important, because if the track forecast is incorrect, forecasts for intensity, rainfall, storm surge, and tornado threat will also be incorrect.
Why is Philippines prone to typhoon visits?
The Philippines is prone to tropical cyclones due to its geographical location which generally produce heavy rains and flooding of large areas and also strong winds which result in heavy casualties to human life and destructions to crops and properties.
Is it helpful to track the path of a typhoon?
An accurate track forecast is important, because if the track forecast is incorrect, forecasts for intensity, rainfall, storm surge, and tornado threat will also be incorrect.
What is the correct order for development of a typhoon?
Like any tropical cyclone, there are few main requirements for typhoon formation and development: (1) sufficiently warm sea surface temperatures, (2) atmospheric instability, (3) high humidity in the lower to middle levels of the troposphere, (4) enough Coriolis effect to develop a low pressure center, (5) a pre- …
What can we observe during a typhoon?
Land-based observations of pressure and wind can show how quickly a tropical cyclone is decaying as it moves inland. Their rainfall reports show where significant rainfall is occurring, and can be an alert for possible flooding.
What does PAGASA do after a disaster?
We deliver reliable and relevant weather-related information, products and services to develop communities resilient to typhoons, floods, rain-induced landslides, storm surges, extreme climatic events, climate change and astronomical hazards.
How does PAGASA’s public storm warning system work?
To help citizens prepare for the onslaught of the storms, PAGASA issues Public Storm Warning Signals that indicate the intensity, the areas that will be affected and the forecast direction and speed of the tropical storm or typhoon. The public storm warning system (PSWS) is as follows:
How does PAGASA use geographic information system in tracing?
The process of mapping the tropical cyclone warning signal is now made easier and faster for Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). This is through the use of Geographic Information System or GIS which automates mapping of places under cyclone signals.
Who is the chief of PAGASA Weather Division?
PAGASA Weather Division Chief Esperanza Cayanan demonstrates the Geographic Information System. The process of mapping the tropical cyclone warning signal is now made easier and faster for Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
Where are the Doppler radar stations in PAGASA?
PAGASA installed its first Doppler weather radar station in Baler, Aurora and another in Baguio. The new weather radars can monitor the typhoon and its movements, amount of rainfall either moderate or heavy and real-time atmospheric forecasts using a visual radar monitor, an example was that of Typhoon Basyang in 2010.
