Midnattssol in english is which natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle?
Midnight sun The midnight sun is a natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle, when the sun remains visible at the local midnight. Around the summer solstice (approximately 21 June in the Northern Hemisphere and 22 December in the Southern Hemisphere) the sun is visible for the full 24 hours, given fair weather. The number of days per year with potential midnight sun increases the closer towards either pole one goes. Although approximately defined by the polar circles, in practice the midnight sun can be seen as much as 55 miles (90 km) outside the polar circle, as described below, and the exact latitudes of the farthest reaches of midnight sun depend on topography and vary slightly year-to-year.
Climate of Australia Australia's climate is governed largely by its size and by the hot, sinking air of the subtropical high pressure belt. This moves north and south with the seasons, so that the rainfall pattern over Australia is highly seasonal. Australia's rainfall is the lowest of all continents except Antarctica. But it is variable, with frequent droughts lasting several seasons—thought to be caused in part by the El Niño-Southern Oscillation. The climate varies widely due to its large geographical size, but by far the largest part of Australia is desert or semi-arid. Only the south-east and south-west corners have a temperate climate and moderately fertile soil. The northern part of the country has a tropical climate, varied between tropical rainforests, grasslands and part desert.
