The dry season is a yearly period of low rainfall, especially in the tropics . The weather in the tropics is dominated by the tropical rain belt , which moves from the northern to the southern tropics and back over the course of the year. The temperate counterpart to the tropical dry season is summer or winter .

38-544: A long dry season. Local geography may substantially modify these climate patterns, however they can. During the dry season, humidity is very low, causing some watering holes and rivers to dry up. This lack of water (and lack of food supply) may force many grazing animals to migrate to more fertile spots. Examples of such animals are: zebras , elephants , giraffes , hippos , rhinos , antelopes and wildebeest , wild water buffaloes , African buffaloes , gaur , tapirs , emus , ostriches , rheas , and kangaroos . Because of
57-643: A model for the behaviour of rivers further south when they were in something closer to a virgin state. In 2016 the Queensland Government purchased Springvale Station, a 56,295-hectare (139,110-acre) property in Lakeland . Springvale Station was purchased to add to the state's protected area network and complement activities being taken to reduce sediment run-off entering the Normanby River catchment . The Erosion Management Plan will inform
76-609: Is an Australian Aboriginal language of Hope Vale and the Cooktown area. The language region includes the local government area of the Aboriginal Shire of Hope Vale and the Shire of Cook , particularly the localities of Cape Bedford , Battle Camp and sections of the Normanby River and Annan River . Dry season The tropical rain belt lies in the southern hemisphere roughly from November to March; during that time
95-496: Is no public access on the Nature Refuge. The small towns of Lakeland , Laura and Lakefield , several homesteads and remote communities are within the catchment. The Normanby basin is almost entirely used for the grazing of beef cattle on large stations - mostly worked by Aborigines . The density of cattle is very low, as are rents . The soils , being mostly ancient lateritic Orthents , are totally unsuitable for
114-584: Is still dry enough during the dry season that tropical rainforests cannot grow. The combined river system descends from a peak elevation of 622 metres (2,041 ft) AHD to sea level, with a combined course from source to mouth of over 490 kilometres (300 mi). While one source considers the Normanby River system as the third largest river in Australia, the Australian Government agency , Geoscience Australia , does not assess
133-1085: The East Normanby River , the West Normanby River , the East Normanby River North Branch , the East Normanby River South Branch and the Granite Normanby River , is a river system in Far North Queensland , Australia. This area is also referred to as the Norman-Laura Catchment and Norman Sub-Basin. With its headwaters in the Great Dividing Range west of Wujal Wujal in the Wet Tropics of Queensland ,
152-542: The Rinyirru National Park , which covers as much as a fifth of the river's basin and is completely impassable during the wet season between November and May. The Rinyirru National Park consists of large wetlands which possess a high diversity of fish species. Near its mouth, the Normanby River flows very slowly and forms a large delta , which is almost inaccessible even during the dry season as there are no roads – even unsealed ones. This land, though,
171-451: The Tropic of Cancer and as far south as the Tropic of Capricorn . Near these latitudes, there is one wet season and one dry season annually. At the equator there are two wet and two dry seasons, as the rain belt passes over twice a year, once moving north and once moving south. Between the tropics and the equator, locations may experience a short wet or a long wet season; and a short dry or
190-702: The Laura River, the Normanby River system is the fourth largest river system in the Great Barrier Reef catchment, with the third largest mean annual discharge into the Reef. Consequently almost all scientific research into the flow and hydrology of the Normanby basin has been done with the health of the reef rather than the river per se in mind. The fact that the Normanby is completely free of dams means that Australian Government studies have used it as
209-621: The Normanby River is formed by the confluence of the East and West Branches of the river at an elevation of 125 metres (410 ft) AHD . The river flows generally north-northwestw through seasonally flooded savanna grassland to reach its mouth in Princess Charlotte Bay about 150 kilometres (93 mi) northwest of Cooktown . The river is joined by 18 tributaries including the Laura River . The river flows through

#1732771953160228-569: The Normanby River system within the ten longest rivers in Australia nor within the three longest continuous river systems in the country. The river may be the largest river flowing into the Coral Sea . The Normanby River system has less than half the flow of the Murray and Mitchell Rivers - though data regarding its flow are sparse with less than a third of the 24,408-square-kilometre (9,424 sq mi) catchment area gauged. Together with

266-568: The disease to spread more easily. New data shows that in the seasonal parts of the South American Amazon rainforest , foliage growth and coverage varies between the dry and wet seasons—with about 25% more leaves and faster growth in the dry season. Researchers believe that the Amazon itself has an effect in bringing the onset of the wet season: by growing more foliage, it evaporates more water. However, this growth appears only in
285-508: The future management planning and activities to be delivered on Springvale Station, as well as identifying potential investment and collaboration opportunities for erosion control on the property. Springvale Station Nature Refuge provides important habitat for endangered or vulnerable flora and fauna including the Cooktown orchid , ghost bat , northern quoll , red goshawk , spectacled flying-fox , spotted-tailed quoll , Semon's leaf nosed bat and large eared-horseshoe bat . There
304-571: The growing sugar cane , which is the principal crop in tropical Australia. Tourism and maintenance of transport infrastructure after regular floods are important to the area. The estuarine areas support commercial and recreational fisheries. The river was named by William Hann in September 1872 in honour of George Phipps, 2nd Marquess of Normanby , who served as the third Governor of Queensland between 1871 and 1874. Guugu Yimithirr (also known as Koko Yindjir, Gugu Yimidhirr, Guguyimidjir)
323-505: The lack of water in the plants, bushfires (wildfires) are common. Data shows that in Africa the start of the dry season coincides with a rise in the cases of measles —which researchers believe might be attributed to the higher concentration of people in the dry season, as agricultural operations are all but impossible without irrigation. During this time, some farmers move into cities, creating hubs of higher population density, and allowing

361-503: The northern tropics have a dry season with sparser precipitation , and days are typically sunny throughout. From May to September, the rain belt lies in the northern hemisphere, and the southern tropics have their dry season. Under the Köppen climate classification , for tropical climates , a dry season month is defined as a month when average precipitation is below 60 millimetres (2.4 in). The rain belt reaches roughly as far north as
