Why does the southern hemisphere have winter




















In fall, the weather in South Africa is warm and dry, with only a tiny chance of rain. Argentina is home to the Tierra del Fuego archipelago, which is the southernmost point of South America and is nicknamed the End of the World.

The weather can be severe here. Water conducts and retains heat better than land, which helps explain why the Southern Hemisphere has warmer fall and winter months.

Australia The northern part of Australia has a tropical climate, which means fall and winter are pretty warm and dry, while the southern regions are cooler and have rainy winters. South Africa In fall, the weather in South Africa is warm and dry, with only a tiny chance of rain.

In winter, the Sun is lower in the sky, and sunlight is spread out over a larger area. During spring and autumn, both hemispheres receive about the same amount of sunlight. At the equator, the temperature variation is much smaller throughout the year, and it is common to consider just two seasons: dry and wet or monsoon.

For observers right at the north pole and the south pole, there are only two seasons — an almost six-month long winter night followed by an almost six-month long summer day! In Barrow, Alaska, the northernmost city in the U. The city is in total darkness between mid-November and January. Seasons in Alaska Sometimes, seasons are determined by both natural and man-made activity. In the U. Ritu A ritu is a season in the traditional Hindu calendar, used in parts of India.

There are six ritu: vasanta spring ; grishma summer ; varsha rainy or monsoon ; sharat autumn ; hemant pre-winter ; and shishira winter.

Seasons can be natural, like hurricane season, which is the time of year when hurricanes are most likely to develop. Seasons can also be artificially created, like hunting season, which is the time of year a community allows people to hunt certain wild animals. Meteorological Seasons Meteorologists, scientists who study the weather, divide each of the seasons into three whole months.

Spring begins March 1, summer June 1, autumn September 1, and winter December 1. Atlantic hurricane season runs from June 1 to November Monsoon usually refers to the winds of the Indian Ocean and South Asia, which often bring heavy rains. Also called the spring equinox. December 22 in the Northern Hemisphere, June 22 in the Southern Hemisphere longest night of the year and the beginning of winter.

This being said, the Earth is at its closest point distance wise to the Sun in January called the Perihelion and the furthest in July the Aphelion.

But this distance change is not great enough to cause any substantial difference in our climate. This is why the Earth's Near June 21st, the summer solstice, the Earth is tilted such that the Sun is positioned directly over the Tropic of Cancer at This situates the northern hemisphere in a more direct path of the Sun's energy. What this means is less sunlight gets scattered before reaching the ground because it has less distance to travel through the atmosphere.

In addition, the high sun angle produces long days. The opposite is true in the southern hemisphere, where the low sun angle produces short days. Furthermore, a large amount of the Sun's energy is scattered before reaching the ground because the energy has to travel through more of the atmosphere. Therefore near June 21st, the southern hemisphere is having its winter solstice because it "leans" away from the Sun.

Advancing 90 days, the Earth is at the autumnal equinox on or about September 21st. As the Earth revolves around the Sun, it gets positioned such that the Sun is directly over the equator. Basically, the Sun's energy is in balance between the northern and southern hemispheres. The same holds true on the spring equinox near March 21st, as the Sun is once again directly over the equator.
