Urban sociologyUrban sociology is the sociological study of cities and urban life. One of the field’s oldest sub-disciplines, urban sociology studies and examines the social, historical, political, cultural, economic, and environmental forces that have shaped urban environments. Like most areas of sociology, urban sociologists use statistical analysis, observation, archival research, U.S.
PrecipitationIn meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls from clouds due to gravitational pull. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and "precipitates" or falls. Thus, fog and mist are not precipitation but colloids, because the water vapor does not condense sufficiently to precipitate.
Planetary equilibrium temperatureThe planetary equilibrium temperature is a theoretical temperature that a planet would be if it was in radiative equilibrium, typically under the assumption that it radiates as a black body being heated only by its parent star. In this model, the presence or absence of an atmosphere (and therefore any greenhouse effect) is irrelevant, as the equilibrium temperature is calculated purely from a balance with incident stellar energy. Other authors use different names for this concept, such as equivalent blackbody temperature of a planet.
Intertropical Convergence ZoneThe Intertropical Convergence Zone (ITCZ ɪtʃ ), known by sailors as the doldrums or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It encircles Earth near the thermal equator though its specific position varies seasonally. When it lies near the geographic Equator, it is called the near-equatorial trough. Where the ITCZ is drawn into and merges with a monsoonal circulation, it is sometimes referred to as a monsoon trough, a usage that is more common in Australia and parts of Asia.
TownA town is a human settlement where people live. It refers to the totality of human community with all the social, material, organizational, spiritual, and cultural elements that sustain it. Towns are generally larger than villages and smaller than cities, though the criteria to distinguish between them vary considerably in different parts of the world. The word "town" shares an origin with the German word Zaun, the Dutch word tuin, and the Old Norse tún.
SiliguriSiliguri, ˈʃiliɡuɽi) is a major tier-II city in West Bengal. It forms "Twin Cities" with the neighbouring district capital of Jalpaiguri. The city spans areas of the Darjeeling and Jalpaiguri districts in the Indian state of West Bengal. Known as the "Gateway of Northeast India", Siliguri is popular for three Ts: tea, timber and tourism. It is located on the banks of the Mahananda River and the Teesta River at the foothills of the Himalayas. Siliguri is the third largest urban agglomeration in West Bengal, after Kolkata and Asansol.
