A climate which is typical of equatorial and tropical regions, i.e., one with continually high temperatures with considerable precipitation, at least during part of the year. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
The aggregate of various economic, political, and social policies by which an imperial power maintains or extends its control over other areas or peoples. It includes the practice of or belief in acquiring and retaining colonies. The emphasis is less on its identity as an ideological political system than on its designation in a period of history. (Webster, 3d ed; from Dr. J. Cassedy, NLM History of Medicine Division)
The name of two islands of the West Indies, separated by a narrow channel. Their capital is Basse-Terre. They were discovered by Columbus in 1493, occupied by the French in 1635, held by the British at various times between 1759 and 1813, transferred to Sweden in 1813, and restored to France in 1816. Its status was changed from colony to a French overseas department in 1946. Columbus named it in honor of the monastery of Santa Maria de Guadalupe in Spain. (From Webster's New Geographical Dictionary, 1988, p470 & Room, Brewer's Dictionary of Names, 1992, p221)
A former branch of knowledge embracing the study, description, and classification of natural objects (as animals, plants, and minerals) and thus including the modern sciences of zoology, botany, and mineralogy insofar as they existed at that time. In the 17th, 18th, and 19th centuries it was much used for the generalized pursuit of certain areas of science. (Webster, 3d ed; from Dr. James H. Cassedy, NLM History of Medicine Division)
The longterm manifestations of WEATHER. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
A measure of the amount of WATER VAPOR in the air.
Any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). It may result from natural factors such as changes in the sun's intensity, natural processes within the climate system such as changes in ocean circulation, or human activities.
Divisions of the year according to some regularly recurrent phenomena usually astronomical or climatic. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
The effect of GLOBAL WARMING and the resulting increase in world temperatures. The predicted health effects of such long-term climatic change include increased incidence of respiratory, water-borne, and vector-borne diseases.
A climate characterized by COLD TEMPERATURE for a majority of the time during the year.
Increase in the temperature of the atmosphere near the Earth's surface and in the troposphere, which can contribute to changes in global climate patterns.
A functional system which includes the organisms of a natural community together with their environment. (McGraw Hill Dictionary of Scientific and Technical Terms, 4th ed)
Water particles that fall from the ATMOSPHERE.
Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
The motion of air relative to the earth's surface.
El Nino-Southern Oscillation or ENSO is a cycle of extreme alternating warm El NiƱo and cold La Nina events which is the dominant year-to-year climate pattern on Earth. Both terms refer to large-scale changes in sea-surface temperature across the eastern tropical Pacific. ENSO is associated with a heightened risk of certain vector-borne diseases.

The solid substance formed by the FREEZING of water.
A thick mass of ICE formed over large regions of land; RIVERS; LAKES; ponds; or SEAWATER.
Diseases that are underfunded and have low name recognition but are major burdens in less developed countries. The World Health Organization has designated six tropical infectious diseases as being neglected in industrialized countries that are endemic in many developing countries (HELMINTHIASIS; LEPROSY; LYMPHATIC FILARIASIS; ONCHOCERCIASIS; SCHISTOSOMIASIS; and TRACHOMA).
The branch of medicine concerned with diseases, mainly of parasitic origin, common in tropical and subtropical regions.
The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms.
Infections or infestations with parasitic organisms. They are often contracted through contact with an intermediate vector, but may occur as the result of direct exposure.
Woody, usually tall, perennial higher plants (Angiosperms, Gymnosperms, and some Pterophyta) having usually a main stem and numerous branches.
The science of developing, caring for, or cultivating forests.
Non-frontal low-pressure systems over tropical or sub-tropical waters with organized convection and definite pattern of surface wind circulation.
The flow of water in enviromental bodies of water such as rivers, oceans, water supplies, aquariums, etc. It includes currents, tides, and waves.
A great expanse of continuous bodies of salt water which together cover more than 70 percent of the earth's surface. Seas may be partially or entirely enclosed by land, and are smaller than the five oceans (Atlantic, Pacific, Indian, Arctic, and Antarctic).
Degree of saltiness, which is largely the OSMOLAR CONCENTRATION of SODIUM CHLORIDE plus any other SALTS present. It is an ecological factor of considerable importance, influencing the types of organisms that live in an ENVIRONMENT.
A vertical distance measured from a known level on the surface of a planet or other celestial body.
A sport involving mountain climbing techniques.
The variety of all native living organisms and their various forms and interrelationships.
An acute febrile disease transmitted by the bite of AEDES mosquitoes infected with DENGUE VIRUS. It is self-limiting and characterized by fever, myalgia, headache, and rash. SEVERE DENGUE is a more virulent form of dengue.
