| United States Pacific Island Wildlife Refuges | Baker, Howland, and Jarvis Islands: equatorial; scant rainfall, constant wind, burning sun Johnston Atoll and Kingman Reef: tropical, but generally dry; consistent northeast trade winds with little seasonal temperature variation Midway Islands: subtropical with cool, moist winters (December to February) and warm, dry summers (May to October); moderated by prevailing easterly winds; most of the 1,067 mm (42 in) of annual rainfall occurs during the winter Palmyra Atoll: equatorial, hot; located within the low pressure area of the Intertropical Convergence Zone (ITCZ) where the northeast and southeast trade winds meet, it is extremely wet with between 4,000-5,000 mm (160-200 in) of rainfall each year |
| Uruguay | warm temperate; freezing temperatures almost unknown |
| Uzbekistan | mostly midlatitude desert, long, hot summers, mild winters; semiarid grassland in east |
| Vanuatu | tropical; moderated by southeast trade winds from May to October; moderate rainfall from November to April; may be affected by cyclones from December to April |
