When it is winter for example is it winter all over earth?

Question

Or it it summer on the other side??

Answer 1

Only the northern and southern hemispheres experience seasonal change, climate and day-length are pretty consistent at the equator. When it is winter in the northern hemisphere (the US, Europe, Canada, etc.) it is summer in the southern hemisphere. Differences in temperature and daylength are due to the way the earth is tilted on its axis as well as its rotation around the sun.

G'day Nobody,

Thank you for your question.

Winter is defined as December, January, February in the Northern Hemisphere and June, July and August in the Southern Hemisphere. My birthday on June 21 is the shortest day of the year in Australia in the Southern hemisphere. If I lived in the northern hemisphere, it would be the longest.

Astronomically, winter starts on the shortest day of the year called the winter solstice which is either June 21 in the Southern Hemisphere or December 21 in the Northern Hemisphere.

The tilt of the earth's axis relative to its orbital plane has a dramatic effect on the weather. The popular belief that winter is caused by the Earth being farther from the Sun than in summer is not true. In fact, in the Northern Hemisphere, winter occurs when the Earth is its closest to the Sun.

The earth is tilted at an angle of 23°27' (23 degrees 27 minutes) to the plane of its orbit, and this causes different latitudes on the Earth to directly face the Sun as the Earth moves through its orbit. It is this variation that primarily brings about the seasons. When it is winter in the Northern Hemisphere, the Southern Hemisphere faces the Sun more directly and thus experiences warmer temperatures than the Northern Hemisphere.

During winter in either hemisphere, sunlight hits that hemisphere at an oblique angle. In regions experiencing winter, the same amount of solar radiation is spread out over a biger area (see Effect of sun angle on climate). This effect is compounded by the larger distance that the light must travel through the atmosphere, allowing the atmosphere to filter more of this already limited heat.

I have attached sources for your reference.

Answer 3

Imagine the sun from the side view. Now picture the solar equator reaching out from it.

O ------ (thats meant to be in the middle)

In summer the earth is "below" this line which makes the northern hemisphere more exposed (longer days).

In Winter the earth is above the solar eliptic which means the northern hemisphere is less exposed, hence shorter days, colder weather, general wintery feeling etc.

Answer 4

We don't experience seasonal changes any time of the year at the equatorial regions do you know?

It is winter in June at the southern hemisphere and summer in the northern hemisphere. Around december, it is the opposite.

Answer 5

When it is Winter in the Northern Hemisphere, it is Summer in the Southern Hemisphere, and the reverse.

This is because of the tilt of our planet on it's axis.

Answer 6

When it is winter in the Northern Hemisphere, it is Summer
in the Southern Hemisphere...

Answer 7

Summer on the other side

Answer 8

Nope, N hemisphere with its autumn slowly approaches to the winter, while in the S they are heating up, so to speak, they have spring in the S at the moment. It is just opposite.

Answer 9

always thought it was summer in the souther hemisphere and winter in the northern

Answer 10

It depends on what part of theworld u live in...
NO,, it's not winter every where all over the earth at the same time.
