A tropical savanna is a grassland biome located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes, with average temperatures remaining at or above 18 °C (64 °F) all year round, and rainfall between 750 millimetres (30 in) and 1,270 millimetres (50 in) a year.They are widespread on Africa, and are found in India, the northern parts of South …

Southern Africa lies outside of the tropical zone and boasts varying climates, ranging from desert to subtropical. The coastal regions display the typical facets of a Mediterranean-type climate, with rainfall occurring only in winter.
Climate zones and ecoregions Southern Africa has a transition to semi-tropical or temperate climates (green), and more desert or semi-arid regions, centered on Namibia and Botswana.
These are the bioclimatic zones known as the Saharan, Sahelian, Sudanian, Guinean, and Guineo-Congolian Regions, shown in the map above. The lines between these regions represent more of a transition along a continuous ecological gradient than sharp boundaries.
Most of it is a vast plateau, with only ten percent of its land area below an altitude of 500 feet. Near the equator are humid rainforests, but north and south of that band, most of sub-Saharan Africa is savanna, grasslands with scattered trees. In the south, the Kalahari Desert stretches along the Atlantic coast.
Where in Sub-Saharan Africa are Mediterranean type climates located? Southern Africa lies outside of the tropical zone and boasts varying climates, ranging from desert to subtropical. The coastal regions display the typical facets of a Mediterranean-type climate, with rainfall occurring only in winter.Dec 2, 2021

The six main climate zones of Africa are found to the north and south of the equator, namely, Equatorial, Humid Tropical, Tropical, Semi- desert (Sahalian), Mediterranean and Desert. A climate region is an area with similar temperature and rainfall.
The lowland climates of West Africa are characterized by uniformly high sunshine and high temperatures throughout the year; mean annual temperatures are usually above 18°C. Areas within 10° of the equator have a mean annual temperature of about 26°C with a range of 1.7 – 2.8°C; the diurnal range is 5.6 – 8.3°C.

The Sub-Saharan Africa region describes the part of the African continent situated geographically south of the Sahara and therefore comprises – according to the definition of the United Nations – 49 of the 54 African states.Jun 22, 2019
Sub-Saharan Africa has many geographic features, including the Sahel region, savannahs, arid lowland terrain, and tropical rainforests. It also includes the longest rivers and largest lakes on the continent.Oct 28, 2021
What landforms are in sub-Saharan Africa? Subsaharan Africa is a realm of plateaus and basins with four main river systems. Mountain ranges, volcanic peaks, and large lakes are found in or along the rift valleys of eastern Africa. The rift valleys were created by tectonic activity.Nov 30, 2021
A subarctic climate has little precipitation, and monthly temperatures which are above 10 °C (50 °F) for one to three months of the year, with permafrost in large parts of the area due to the cold winters. Winters within subarctic climates usually include up to six months of temperatures averaging below 0 °C (32 °F).
The climate is characterized by hot, dry summers and cool, wet winters.
Places with more than three months of average daily temperatures above 10 °C (50 °F) and a coldest month temperature below −3 °C (27 °F) and which do not meet the criteria for an arid or semi-arid climate, are classified as continental.
A tropical savanna is a grassland biome located in semi-arid to semi- humid climate regions of subtropical and tropical latitudes, with average temperatures remaining at or above 18 °C (64 °F) all year round, and rainfall between 750 millimetres (30 in) and 1,270 millimetres (50 in) a year.
Over historical time spans, there are a number of nearly constant variables that determine climate, including latitude, altitude, proportion of land to water, and proximity to oceans and mountains. All of these variables change only over periods of millions of years due to processes such as plate tectonics.
Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, which includes the ocean, land, and ice on Earth.
Climate is the long-term average of weather, typically averaged over a period of 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, ...
The northward departure of 13 wader species was studied in the springs of 1985, 1986 and 1988. Waders left the area in the late afternoon. A total of 31 000 waders were observed heading northwards, with those species wintering locally in largest numbers being most common. The majority of wader species showed fairly short periods of departure and unimodal departure peaks. Redshanks Tringa totanus and dunlin Calidris alpina departed over extended periods. Average departure dates of species correlated possitively with the estimated midpoints of ranges in breeding latitude (c2 d per ° latitude). Timing of departure is largely under internal, not direct environmental, control. -from Authors
It is widely accepted that the timing of migration in avian species is determined by both external and endogenous factors. The possibility that individuals of the same species may have differing migration thresholds, however, has not been explored in such detail. This study shows that consistency from year to year in the migratory pattern of individual Bewick's swans, Cygnus columbianus bewickii, exceeds a level referable to chance, despite fluctuation in the data due to other variables. Photoperiod controls the timing of migration in many species and it is suggested that the factor that regulates the onset of migratory activity in individual swans is the individuals' response threshold to changes in daylength. A comparison of the arrival and departure dates obtained for each bird showed an inverse relationship between the two sets of data: swans that arrived early were more likely to leave late. Consideration of the data obtained for parents and their full-grown offspring indicated that the offspring may have acquired, either genetically or by learning, their parents' migratory thresholds. Heritability levels were low, however, accounting for 10–20% of the variation in the arrival and departure data.
bodies of water where rivers flow into the ocean, mixing saltwater with fresh water. Salinity fluctuates daily due to the tides and changes in river flow. Estuaries are sheltered from the heavy waves of the ocean and provide habitat for many plants, which provide food for shellfish, birds, and fish. salt marshes.
At each trophic level, most of the energy input is either used for maintenance or lost as heat. A trophic level will only have about 10% of the energy content, organisms, and biomass compared to the level below it.
