Climate data for Singapore (1991–2020 normals, extremes 1929–1941 and 1948–present) Month Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
A weather station was set up in Outram that year to measure monthly rainfall, marking the beginning of the "climate station" used to compile climatological data for Singapore. [4] The responsibility for collecting weather data was assigned to a new Meteorological Branch under the Malayan Survey Department in 1927. [5]
Specific humidity (or moisture content) is the ratio of the mass of water vapor to the total mass of the air parcel. [15] Specific humidity is approximately equal to the mixing ratio, which is defined as the ratio of the mass of water vapor in an air parcel to the mass of dry air for the same parcel.
The humidity adjustment approximately amounts to one Fahrenheit degree for every millibar by which the partial pressure of water in the atmosphere exceeds 10 millibars (10 hPa). At the time the humidex was originally developed in 1965, Canada was still on the Fahrenheit scale , and thus the humidex was originally based on that.
A humid subtropical climate is a subtropical-temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia ...
An aridity index (AI) is a numerical indicator of the degree of dryness of the climate at a given location. The American Meteorological Society defined it in meteorology and climatology, as "the degree to which a climate lacks effective, life-promoting moisture".
A few hours later during the early morning hours of Feb. 4, as the temperature dipped further to 10 degrees below zero, this broke that date's record low of 2 degrees below zero from 1886.
