Which season begins in the northern hemisphere when the sun reaches its greatest distance southe of the equator?
The 'perihelion' is the point during the orbit of Earth when our planet is closest to the sun. The date of the perihelion was January 3rd. The point when Earth is farthest from the sun is called the 'aphelion.' It will occur on July 7th. It does not matter if you are in the Northern Hemisphere or the Southern Hemisphere. The changing of the seasons is due to the tilt of the Earth's axis, not its varying proximity to the sun. The dates of the perihelion and the aphelion actually change over long periods of time. Our twelve month calendar, the time it takes to go completely around the sun, is called a 'tropical' year. The time it takes to go from one perihelion to the next is called an 'anomalistic' year, and an anomalistic year is about 25 minutes longer than the tropical year. This means that the date of the perihelion changes by one day every 58 years, and 'regresses' entirely through a tropical in approximately 21,000 years. It is thought by many scientists that such a change might have a long term effect on the Earth's climate.
How and why does summer and winter occur?
The Earth has seasons because it is tilted about 23.5 degrees from straight up and down. Think of the Earth as a spinning top, tipped over to one side. It remains tipped in the same direction as it travels around the Sun. This means that sometimes the northern hemisphere of the Earth is pointing towards the Sun, and sometimes it is pointing away. When the northern half of the Earth is pointing towards the Sun, the northern hemisphere of the Earth gets more direct sunlight. We call this the "summer" season for the north. At this same time, the southern half of the Earth is pointed away from the Sun, so people in the southern hemisphere get less direct sunlight. We call this "winter" for the southern hemisphere. So, because of the tilt of the Earth's axis, the seasons in the south are the opposite of those in the north. _-Bakonawa-_ The seasons occur because the earth rotates about its axis at and angle of 23.5 degrees (there is a wobble that affects this tilt, but it takes thousands of years). Since we are at an angle to the suns rays we receive more or less direct light during different times of the year. In the northern hemisphere, during the summer, we are angled towards the sun during the day, receiving more of the direct solar energy. In the winter we are angled away from the sun during the day, the sunshine is spread more thinly over the land and we receive less energy. the southern hemisphere has its summer during the north's winter and vice versa.
Is the sun closer to the earth in the summer time?
In the southern hemisphere the Earth and Sun are closest during the hotter season (call it summer if you will). Perihelion is on or around January 4. Your location on earth receives more direct rays from the Sun in summer (hence the higher temperatures). In the northern hemisphere this occurs when the Sun and the Earth are farther from each other than in the northern hemisphere winter. Aphelion is on or around July 4.
What month is summer solstice?
In 2011, the sun will reach the solstices at 1:16 PM ET on June 21, and at 12:30 AM ET on December 22. Which of those you call the "Summer" solstice depends on whether you'll be living in the northern or southern Hemisphere in 2011. -- Northern summer begins on June 21. -- Southern summer begins on December 22.
Who do cyclones effect?
cyclones effect mostly people in the southern hemisphere because people in the northern hemisphere call them hurricanes
What do you call the imaginary line that divides the north and south halves of earth?
The equator divides the earth between the Northern Hemisphere and the Southern Hemisphere
What do you call one half of the earth?
A hemisphere is one half of the sphere that makes up Earth's surface.
What do you call the place can be found above the equator?
The northern hemisphere
What do you call the first day of summer in the northern hemisphere?
Blah
What Hemisphere is Pleasant Valley Ca considered to be in?
Pleasant Valley, California is considered to be in the Northern Hemisphere, which encompasses the majority of Earth's land, all of North America, and, therefore, all of California. The two hemispheres are divided by an imaginary line we call the equator. Anything south of the equator is part of the Southern Hemisphere, and similarly anything north of the equator is part of the Northern Hemisphere.
What do you call the upper part that is being divided by the equator?
The northern hemisphere.
What do we c alled the half of the eath?
By my understanding, the earth is divided into to 2 halves by the Equator (the line that runs from west to east around the earth) we call this halves Hemispheres...There is the "northern hemisphere" and "southern hemisphere"...The Greenwich meridian (the line that runs from north to south around the earth) divides the earth into the "western hemisphere" and "eastern hemisphere"..
What do you call a half sphere?
Half a sphere has a prefix of "hemi" as in the Northern Hemishere.
How do you call the region that lies on the latitudes between equator and polar region?
The region between the equator and the north pole is called the "northern Hemisphere". The region between the equator and the south pole is called the "southern Hemisphere". The two of them put together cover the whole earth.

Does which hemisphere affect cyclones and hurricanes rotation?
Yes - a cyclone is a Southern hemisphere word for what is usually called a hurricane in the Northern hemisphere. Cyclones are the same thing as hurricanes, and for that matter, as tropical storms and typhoons too, but it's important to know that whilst they all mean the same kind of weather event, the word 'cyclone' originates from the Southern hemisphere. A cyclone is an appropriate name for such an event in the Southern hemisphere (eg Cyclone Nargis that hit Myanmar) because here, the weather system rotates clockwise. For us and my students in the UK in the Northern hemisphere, however, it sounds counter intuitive to call these systems cyclones because in the Northern hemisphere they rotate anti-clockwise and so they are traditionally known as hurricanes (eg Hurricane Katrina that hit the US). The rotation is caused by the earth's spin, known as the 'coriolis effect', which causes the airflow patterns to be affected, with the direction of rotation being determined by whichever hemisphere the hurricane spawns in.
