Tropical Storm Shanshan (2013)
Tropical Storm Shanshan, known in the Philippines as Tropical Depression Crising, was a weak tropical cyclone which affected the southern Philippines in mid February 2013. The second named storm of the 2013 Pacific typhoon season, Shanshan developed from a tropical depression on February 18 while located northeast of the Morotai Island. Environmental conditions were marginally favourable that it remained a weak tropical depression while moving west-northwest. The depression struck Mindanao and Palawan on February 19–20, before emerged into the South China Sea. Despite environmental conditions remained marginally favourable, the system briefly achieved tropical storm status late on February 21, and received the name ''Shanshan''. Conditions soon deteriorated, Shanshan weakened back to a tropical depression on the next day and dissipated on February 23. Although Shanshan remained weak when striking the Philippines, it still brought rainfall and caused flooding and landslides. Provi ...

Subtropical Ridge
The horse latitudes are the latitudes about 30 degrees north and south of the Equator. They are characterized by sunny skies, calm winds, and very little precipitation. They are also known as subtropical ridges, or highs. It is a high-pressure area at the divergence of trade winds and the westerlies. Origin of the term A likely and documented explanation is that the term is derived from the "dead horse" ritual of seamen (see Beating a dead horse). In this practice, the seaman paraded a straw-stuffed effigy of a horse around the deck before throwing it overboard. Seamen were paid partly in advance before a long voyage, and they frequently spent their pay all at once, resulting in a period of time without income. If they got advances from the ship's paymaster, they would incur debt. This period was called the "dead horse" time, and it usually lasted a month or two. The seaman's ceremony was to celebrate having worked off the "dead horse" debt. As west-bound shipping from E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone Wind Signals
The Tropical Cyclone Wind Signals (TCWS, or simply ''wind signals'' or ''signals''; Filipino: ''Mga Babala ng Bagyo'') are tropical cyclone alert levels issued by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) to areas within the Philippines that may be affected by tropical cyclone winds and their associated hazards. PAGASA's TCWS system is activated when a tropical cyclone is inside or near the Philippine Area of Responsibility and is forecast to affect the Philippine archipelago. It is a tiered system that has five numbered levels, with higher numbers associated with higher wind speeds and shorter "lead times", which are time periods within which an expected range of wind strength is expected to occur. TCWS signals are issued for specific localities (province or city/municipal level) and are escalated, de-escalated or lifted depending on the expected strength of winds and the movement of the tropical cyclone relative to the affec ...

Philippine Area Of Responsibility
The Philippine Area of Responsibility (PAR) is an area in the Northwestern Pacific where PAGASA, the Philippines' national meteorological agency, monitors weather occurrences. Significant weather disturbances, specifically tropical cyclones that enter or develop in the PAR, are given Philippine-specific names. Boundary The area is bounded by six points namely: * * * * * * This area encompasses almost all of the land territory of the Philippines, except for the southernmost portions of the province of Tawi-Tawi, and some of the country's claimed islands in the Spratlys. The area also includes the main island of Palau, most of Taiwan, as well as portions of the Malaysian state of Sabah and the Japanese prefecture of Okinawa. Function The establishing decree of PAGASA mandates the weather agency to monitor weather occurrences occurring within the PAR. Tropical cyclones are only assigned local names by PAGASA when they enter or develop within the PAR. These names are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Circulation
Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant. The smaller scale weather systems – mid-latitude depressions, or tropical convective cells – occur chaotically, and long-range weather predictions of those cannot be made beyond ten days in practice, or a month in theory (see chaos theory and the butterfly effect). The Earth's weather is a consequence of its illumination by the Sun and the laws of thermodynamics. The atmospheric circulation can be viewed as a heat engine driven by the Sun's energy and whose energy sink, ultimately, is the blackness of space. The work produced by that engine causes the motion of the masses of air, and in that process it redistributes the energy absorbed by the Earth's surface ne ...

Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area. Etymology The etymology of the word monsoon is not w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balabac, Palawan
Balabac, officially the Municipality of Balabac ( tgl, Bayan ng Balabac), is a 2nd class municipality in the province of Palawan, Philippines. According to the 2020 census, it has a population of 42,527 people. The municipality consists of some 36 islands, including the eponymous Balabac Island. The islands are notable for their uncommon indigenous plant and animal species, such as the nocturnal Philippine mouse-deer (or Pilandok). The islands are also home to dugongs, saltwater crocodiles, sawfishes, and sea turtles. Due to its biodiversity, the terrestrial and marine ecosystems of the Balabac archipelago are currently being pushed by scholars to be included in the tentative list of the Philippines for a possible UNESCO World Heritage Site nomination in the future. History Balabac was converted from a municipal district to a full municipality in 1957. Before that, it was a barrio of neighboring Bataraza.

Atmospheric Convection
Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. Overview There are a few general archetypes of atmospheric instability that are used to explain convection (or lack thereof). A necessary (but not sufficient) condition for convection is that the environmental lapse rate (the rate of decrease of temperature with height) is steeper than the lapse rate experienced by a rising parcel of air. When this condition is met, upward-displaced air parcels can become buoyant and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Celebes Sea
The Celebes Sea, (; ms, Laut Sulawesi, id, Laut Sulawesi, fil, Dagat Selebes) or Sulawesi Sea, of the western Pacific Ocean is bordered on the north by the Sulu Archipelago and Sulu Sea and Mindanao Island of the Philippines, on the east by the Sangihe Islands chain, on the south by Sulawesi's Minahasa Peninsula, and on the west by northern Kalimantan in Indonesia. It extends 420 miles (675 km) north-south by east-west and has a total surface area of , to a maximum depth of . South of the Cape Mangkalihat, the sea opens southwest through the Makassar Strait into the Java Sea. The Celebes Sea is a piece of an ancient ocean basin that formed 42 million years ago in a locale removed from any landmass. By 20 million years ago, earth crust movement had moved the basin close enough to the Indonesian and Philippine volcanoes to receive emitted debris. By 10 million years ago the Celebes Sea was inundated with continental debris, including coal, which was shed from a gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
