According to Blackburn and Holford-Strevens (who used Newcomb's value for the tropical year) if the tropical year remained at its 1900 value of 365.242 198 781 25 days the Gregorian calendar would be 3 days, 17 min, 33 s behind the Sun after 10,000 years. Aggravating this error, the length of the tropical year (measured in Terrestrial Time) is ...
The climate is typically equatorial – temperature range over the year is less than three degrees Celsius (-5.4 degree F), and annual rainfall exceeds 1,500 millimetres (60 in). January to April inclusive are less wet than the other months. The backbone of Cebu's hills and mountains can have temperatures lower than the coastal areas.
Of those that made landfall or crossed the Philippines, the average was nine per year. In 1993, a record nineteen typhoons made landfall in the country, making it the most in one year. The fewest per year were four during the years 1955, 1958, 1992, and 1997. [8] PAGASA categorizes typhoons into five types according to wind speed.
The Julian calendar ended up being 11 minutes and 14 seconds longer than the tropical year — the time it takes for seasons to repeat. In the late 16th century, Pope Gregory XIII improved the ...
Aerial view of Bora Bora in French Polynesia Tropical sunset over the sea in Kota Kinabalu in Malaysia. Many tropical areas have both a dry and a wet season. The wet season, rainy season or green season is the time of year, ranging from one or more months when most of the average annual rainfall in a region falls. [9]
The Köppen climate classification is the most widely used climate classification system. [2] It defines a tropical climate as a region where the mean temperature of the coldest month is greater than or equal to 18 °C (64 °F) and does not fit into the criteria for B-group climates, classifying them as an A-group (tropical climate group).

If Man-yi impacts the northern Philippines, it would make for four tropical impacts on the area in 10 days. ... The Philippines is impacted by an average of 20 typhoons a year. So far this year ...
A study of temperature records over the past 300 years [1] suggests that the seasonal year is governed by the anomalistic year rather than the tropical year. This suggestion is surprising because the seasons have been thought to be governed by the tilt of the Earth's axis (see Effect of sun angle on climate). The two types of years differ by a ...
