At the south pole for 2008, the largest ozone "hole" size (27 million square kilometers) was on September 12, the least ozone on a vertical path (100 Dobson units as compared to ~220 for summer values) occurred on October 4.
The north pole should have a similar feature about six months earlier / later, when the Sun is not shining on the north pole, then starts shining on it.
Note that an "ozone hole" is not truly a hole, as there is still some ozone in the atmosphere there.
What else can I help you with?
Why were the winds between 30 degrees and 0 degrees north and south of the equator named trade winds?
The trade winds are the prevailing pattern of easterly surface winds found in the tropics, within the lower portion of the Earth's atmosphere, in the lower section of the tropospherenear the Earth's equator. The trade winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, strengthening during the winter and when the Arctic oscillation is in its warm phase. Historically, the trade winds have been used by captains of sailing ships to cross the world's oceans for centuries, and enabled European empire expansion into the Americas and trade routes to become established across the Atlantic and Pacific oceans.
Are the days longer or shorter in the northern hemisphere right after the autumnal equinox?
In the northern hemisphere, the days become shorter right after the autumnal equinox. This is because the amount of daylight decreases as the hemisphere tilts away from the sun, leading to shorter days and longer nights.
Which hemisphere is tilted toward the sun for the autumnal equinox?
The Tropic of Capricorn.
How does the Coriolis effect relate with hurricanes?
As a consequence of the Coriolis effect large scale wind currents get deflected relative to a pressure gradient, to the right in the southern hemisphere and to the left in the northern hemisphere. As a result, large scale pressure systems rotate, such as hurricanes, which are strong low-pressure systems. This rotation actually allows storms to become better organized and intensify even further. At the equator, where the Coriolis effect is essentially nonexistent storms cannot organize in such a fashion, and so usually nothing more than disorganized bands of weak thunderstorms develop.
Where are bogs found?
Bogs are most abundant in the Northern Hemisphere, especially in a broad belt including the northern part of the deciduous forest zone and the central and southern parts of the boreal forest zone. Farther south, and in drier climates farther inland, they become sporadic and restricted to specialized habitats. To the north, peatlands controlled by mineral soil water (aapa mires) replace them as the dominant wetlands.Bogs are much less extensive in the Southern Hemisphere because there is little land in cold temperate latitudes. In these Southern Hemisphere peatlands, Sphagnum is much less important, and Epacridaceae and Restionaceae replace the Ericaceae and Cyperaceae of the Northern Hemisphere.For the source and more detailed information concerning this issue, click on the related links section indicated below.who cares
During what season in the southern hemisphere does the so-called ozone hole become largest?
Winter, to early spring.
Where was the first tram service in southern hemisphere?
The first tram service in the Southern Hemisphere was established in Melbourne, Australia, in 1884. This system initially used horse-drawn carriages before transitioning to electric trams in the early 20th century. Melbourne's tram network has since become one of the largest and most iconic in the world.
During which time period does the Southern Hemisphere have summer?
In some Southern Hemisphere countires, it's official that Spring arrives with September. That has the advantage that it puts winter's end at a time when the temperature is similar to what it was at winter's beginning (June. 1 in the Southern Hemisphere--December 1 in the Northern Hemisphere). But many have said that, in the Northern Hemisphere, April feels like the first Spring month. I agree. That corresponds to October in the Southern Hemisphere. By April, it's become warm and sunny, and there is sufficient sunlight to luxuriantly bring back the plant-life.
In between June 21 and September 21 days become shorter or longer?
The time period that you are referring to is called the summer solstice. This is the time when the earth's path around the sun has forced the Northern Hemisphere to start pointing directly at the sun. At that point, every part of the Northern Hemisphere sees the sun for more than 12 hours and every part of the Southern Hemisphere sees the sun for less than 12 hours.So the answer is: for the Northern Hemisphere, the days become longer, and for the Southern Hemisphere, the days become shorter.Hope this helps ~ CB
In between September 23 and December 22 do days become shorter or longer?
Days get `longer` between June 21st and December 21st for the southern Hemisphere, while they get shorter for those in the northern hemisphere. Between December 21st and June 21st, the days get longer for those in the northern hemisphere and shorter for those in the southern hemisphere.
Is the days shorter and nights get longer?
In the northern hemisphere, USA and UK included, during Spring the days become longer and the nights become shorter. Conversely, in the southern hemisphere, Australia, and South Africa included , during the same period the days become shorter and the nights become longer. Depending on which side of the Equator you are on , the seasons and daylight hours are reversed. During Autumn (Fall)(northern hemisphere), the whole process is reversed in both hemispheres.
When do cherry fruit become ripe?
The prime season for cherry ripening is in the middle of summer. In the northern hemisphere from July to August. In Australia, New Zealand and the other temperate countries in the southern hemisphere, they ripen around December.
Will the blue whale become extinct?
Blue whale hunting was banned in 1966 by the International Whaling Commission. But, by 1970 330,000 blue whales had been caught & killed in the Antarctic, 33,000 in the rest of the Southern Hemisphere, 8,200 in the North Pacific, and 7,000 in the North Atlantic. The largest original population, in the Antarctic, had been reduced to 0.15% its original count. Now that they are protected and hunting is banned, I dont think they will become extinct.
How old must a horse be to be in the Kentucky Derby?
Race for "three year-olds". However, Thoroughbreds that are born in the Northern Hemisphere technically become a year older on January 1 each year and those born in the Southern Hemisphere turn one year older on August 1.
What does the Southern Cross on the NZ flag mean?
it's not the southern cross, but the UK Flag because New Zealand was first colonised by the British. http://www.worldflags101.com/n/new-zealand-flag.aspx The Southern Cross on the New Zealand flag represents NZ's location in the South Pacific Ocean (the blue background).
Why do four seasons occur?
The cause of the seasons is the tilt of the Earth's axis of rotation (line from one pole to the other) with respect to the plane of its orbit around the Sun. During the course of the year, this changes the length of the day, and the angle of the Sun's rays, for all locations except those in the tropics near the equator.The seasons are not experienced the same way in every location, due to winds, currents, and local weather patterns. The seasons are reversed north or south of the equator : when it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa.Summer: the Sun's rays are more directly overhead, temperatures are warm, days are longerFall : the Sun's rays are less directly overhead, temperatures become cooler, days become shorterWinter: the Sun is farthest from directly overhead, temperatures are lowest, days are shortestSpring: the Sun becomes higher in the sky, temperatures become warmer, days become longer
Did the US become a debtor nation at the end of the world war 2?
The US went from the largest creditor nation to a debtor (eventually largest) during the Reagan administration. Charles Pervo
