The Philippine weather is quite predictable during the summer months, but the same can’t be said about the winters. typhoons and heavy rains are fairly common during the rainy season, while floods are fairly rare. The large number of stations that monitor the weather in the Philippines provides the necessary information for forecasters to make accurate forecasts. But there is one problem with the data collected at these stations: accuracy.
The average time period for the tropical cyclones in the Philippines is around five weeks, while the typhoons can hit the island anywhere from two weeks to a month – making it impossible to get an accurate analysis on the weather during these periods. This uncertainty makes it impossible to make a well-rounded forecast for the Philippine weather, which is often affected by external factors, such as rainfall and clouds. In addition, most of the available data on the Philippine weather are from the rainfall collected at the observation stations.
Rain gauges are widely used in the Philippines to record rainfall, and tropical cyclone numbers are known across the globe, but in the Philippines there are no systematic observations of severe weather events. While the government and private meteorological departments make serious efforts to collect adequate data for scientific research, the shortcomings of the available tools make it difficult to collect reliable and complete statistics. Another major limitation of the available meteorological data is their source. Most rainfall is measured at the dew point, but since the country is largely an island, rain gauges are located at various places that are at higher risk of receiving little rainfall. While the Philippine government has made an effort to collect more and better rainfall data, it needs more systematic observations to be developed.
