1. Typhoon signals and the prevailing meteorological conditions in the Philippines By: Cyril, April, divine

2. What are typhoons signals? A Tropical Cyclone Wind Signal (TCWS) is a plain text warning to particular land area that may experience winds of at least strong breeze in strength on the Beaufort Scale (i.e., 39 km/h, 22 kt or higher) within at most 36 hours from the time the signal is put into effect during the passage of a tropical cyclone. A particular wind signal has an equivalent expected wind threat, length of time (in hours) before onset of expected wind threat, and potential impacts to the locality. The current TCWS system uses five (5) levels of wind signals that are numbered from 1 to 5 , with a higher signal number associated with higher general wind strength and shorter warning lead time.

3. Climate of the Philippines The  Philippines  has five types of  climates :  tropical rainforest ,  tropical monsoon ,  tropical savanna ,  humid subtropical  and  oceanic  (both are in higher-altitude areas) characterized by relatively high temperature, oppressive humidity and plenty of rainfall. There are two  seasons  in the country, the wet season and the dry season, based upon the amount of rainfall. [1]  This is also dependent on location in the country as some areas experience rain all throughout the year 

4. Tropical rain forest The Philippines & Sulu Sea Tropical Forests bioregion is located in the Southeast Asian Forests subrealm of Indomalaya and contains nine ecoregions – Luzon Rainforests [1], Luzon Montane Rainforests [2], Luzon Tropical Pine Forests [3], Palawan Rainforests [4], Mindoro Rainforests [5], Greater Negros-Panay Rainforests [6], Mindanao-Eastern Visayas Rainforests [7], Mindanao Montane Rainforests [8], Sulu Archipelago Rainforests [9] – totaling approximately 30 million hectares of land area. 

5. Tropical monsoon the summer monsoon brings heavy rains to most of the archipelago from May to October. Annual average rainfall ranges from as much as 5,000 millimeters (197 in) in the mountainous east coast section of the country, to less than 1,000 millimeters (39 in) in some of the sheltered valleys. Monsoon rains, although hard and drenching, are not normally associated with high winds and waves .

6. Tropical savanna Metro Manila has a tropical savanna climate with dry winters. Over the course of a year, the temperature typically varies from 22°C in January to 34°C in May. The sky is cloudiest in August and clearest in April. Precipitation is most likely in July and least likely in April.

7. Humid subtropical Humid subtropical climate is characterized by hot and humid summers, and cold to mild winters. Provinces with this type of climate are typically located at or near coastal areas.

8. Oceanic The Climate of the Philippines is tropical and maritime. It is characterized by relatively high temperature, high humidity and abundant rainfall.

9. Quiz time!! 1. what is a typhoon signal? 2. what does the numbered 1 to 5 mean in typhoon signals? 3-6. give 4 climate changes in the Philippines. 7-8 give 2 ecoregions in the tropical rain forest.
