Seasons

This is a more complex answer than most might think. Climate (long term weather) and climate change are a basic factor of 3 main things Obliquity (axial tilt) Precession Rotation (elliptical eccentricity,) They are also referred to as Milankovitch cycles named for the Serbian scientist that theorized and later proved his idea of cyclical climate changes with 26k 41k and 100k events which later were mathematically shown to coincide almost exactly with earths climate history. The...

The Earth is tilted on its axis. 'Summer' (the warmest season) occurs when a hemisphere, either the northern hemisphere or the southern hemisphere, is tilted towards the Sun and thus receives more direct sunlight (the Sun is closer to the zenith and is above the horizon longer). A common misconception is that the seasons have to do with the Earth being closer to the Sun due to the elliptical nature of its orbit. The orbit is elliptical and the Earth is closest...

The seasons begin with Spring, Summer, Fall (Autumn), and then finally Winter. This then becomes a cycle. ...

Four Seasons, Winter. Seasons are a subdivision of a year. The Earth's rotation axis is tilted by 23.4392794383 degrees with respect to the, at different times of a variation in the 180 - 270 deg (mn), longitudes 270 - 360 deg (Winter). The Sun true longitude (Lsun) is derived from Sun mean longitude (Lmean) and Earth mean anomaly (ME). For any input through many Sun true Longitude (Lsun) for the input year 1013 : Year = 2013, Start : UT year =...

The seasons are due to the motion of the Earth around the Sun. So, it may not be surprising that the Sun's position in the sky changes over seasons, due to the motion of the Earth around the Sun. The explanation is simple. All stars in the sky are moving, but the distant stars are so far away that we cannot detect appreciable motion (even when the Earth moves around the Sun). As a result, the positions of distant stars in...

The actual period of winter in the northern hemisphere is 21 December through 21 March. In the southern hemisphere, winter is from 21 June through 21 September, while the northern hemisphere is experiencing summer. Generally speaking, most people in the northern hemisphere think of winter as being in December, January and February while in the southern hemisphere, many people consider winter to be in June, July and August. In fact in Australia (at least) winter officially begins on 1st June and ends on 31st...

Summer. For places between the tropics it's a bit different with zero shadow at times. ...

Spring comes in between the 19th to the 23rd of March and at different times. It changes on a yearly basis because the first official day of spring is the (Spring) Vernal Equinox. This is when the sun is directly above the equator. It rises due East and sets due West and does not do so on the exact same day every year, since the calendar is not exactly 365 precise days every single year. In 2009, spring arrived on March...

Electromagnetic waves hit both the north ans south poles. These are the same rays that hit the rest of the Earth. The difference is in the angle at which they hit. They are more oblique than at the equator, and so they get spread over a bigger area and so heating is less intense. ...

Never.

Anywhere around the equator, the days and nights are always about equal.

Summer is the worst time for snakes in Australia, but they begin to emerge around September, and tend to stay more active until about April, particularly if the weather is warm. ...

No.

It depends on if you're talking about Spring Training or the regular season. Spring Training starts in late February and the regular season begins in April. ...

By some definitions, all countries experience four seasons. The variation in the weather and temperature depends, largely, on the latitude of the country. However, we tend to say that most tropical countries experience only two seasons: wet and dry. This is because temperature varies very little throughout the year, whereas the position of the inter-tropical convergence zone causes one or more distinct wet seasons. This is far more important to these people than slight changes in temperature because the timing of the rain...

A lot of countries experience 4 seasons. All of them are situated away from the Equator, above the Tropic of Cancer and Capricorn. Some examples are the Countries on the Northern America, mainly USA and Canada, most or all of the European countries. Some countries in Asia experience 4 seasons too, such as China, Korea (North and South), Japan. Australia and New Zealand experience 4 seasons too, but their cycle is different from the countries located on the Northern Hemisphere of the...

There can be numerous reasons why it may be more difficult to breathe in the summer, some are, seasonal allergies, ozone, poor air quality, humidity, pollen, open windows leaving in car exhaust fumes and other air pollutents. Cheyzer ...

The tilt on Earth causes it. The orbiting around the sun makes it happen.
