It was invented during world war 2 to increase production. It was called "war time". Basically instead of keeping to one time frame it has you start your day earlier in the summer and the "normal" time it would start in the winter by one hour. The idea was that if someone got to work earlier in the summer they would hopefully stay a little later since there was still daylight. It helped production by %5-10.

It's daytime, because of physics. \n\nTo make this simple, just think that since water takes longer to heat than the earth, the air over water is cooler than the air over land. There's some physics law that says everything will reach an equilibrium in temperature. So, the air above will ocean will be moving towards the land to try to equalize. \n\nIn contrast, at night, the air over land cools faster than the air over water. Thus, the breeze goes into the sea. \n\nGood luck!

The reason there is differing amounts of daylight is that the Earth's axis is tilted with respect to the plane of its rotation about the sun. When the north pole is tilted towards the sun, the northern hemisphere days get longer. The point in the Earth's orbit about the sun where the plane through the Earth's axis that is perpendicular to the Earth's plane of orbit ALSO passes through the sun itself (i.e. the Earth's rotation axis is lined up with the sun, north end closest) is the summer solstice. When the same plane passes through the sun again, only with the south pole closest, that is the winter solstice. At summer solstice, the length of the day is longest in the northern hemisphere. At winter solstice the day is shortest in the northern hemisphere. The opposite is true in the southern hemisphere. On the equator the lengths of the days don't change at all! The further you get from the equator, the more the length of the days change with the seasons.\n\nSo let's talk northern hemisphere. If the longest day is around June 21 (summer solstice) and the shortest day is Dec 21 winter solstice, you can think of the length of the days as changing smoothly from shortest to longest as you move from winter to summer solstice. If you do the geometry to figure out how the length of days changes with the seasons, it looks a lot like a sine wave. It's actually shaped a little differently because the Earth's orbit is not a circle--that would make a sine wave exactly for the length of days--but instead an ellipse. But it's still pretty close to a sine wave. If you look at a sine wave, you'll notice that as the wave approaches the bottom, slows down its descent until it almost "flattens" at the bottom, but not quite. Then after the bottom, it goes up more steeply until somewhere in the spring it is changing as fast as possible (pretty near to the vernal equinox), then begins to slow down again until it hits the peak at the summer solstice. After the summer solstice, the longest day, the length of days begins to fall, slowly at first and then ever faster, until somewhere in fall (pretty near the autumnal equinox) it's changing as fast as it's ever going to. Then it begins to slow down, until it hits the minimum at the winter solstice again. If you look back at the description about, you'll notice that the rate at which the length of days change also varies with the season. In fact, the rate of change is like a sine wave, too, only it's shifted by a season from the wave that describes the rising and falling of the length of the day itself.\n\n\nFor the latitudes farther away from the equator, the amplitude of the sine wave is larger. For the southern hemisphere it is flipped upside down compared to the same latitude in the northern hemisphere. And on the equator, the "sine" curve as zero amplitude--that is, it's a straight line.\n\nIn calculus you would say that the rate of change of a function (the "derivative" of the function with respect to time) tells you how fast the daylight is changing on a given day. And, in calculus you also learn that the rate of change of a sine wave is a cosine wave--or just another sine wave shifted back by 90 degrees. And 90 degrees of the sine wave describing the length of days corresponds to one season on Earth!

I don't know for certain, but it's probably the changing season from winter to spring - as weather fronts alternate between warm and cold with greater frequency, there is simply more opportunity for the wind to claim any given day in March.  As the season turns more consistently warmer, the winds die down overall.

summer time causes more swelling - the heat & humidity, ya know

The French don't like foreigners much but if you speak their language quite well then they like you a lot more.  One thing to know is that every one in Paris goes on holiday in August so the roads are horrendous the first couple of days and the last couple of days so don't plan any long drives then.

The real reason why there are more insects in the summer than the winter is because the summer provides an ideal environment for eggs to hatch.  Hot muggy conditions provide moisture and is more conducive for procreation.  The mortality rate of insects also is less because of these ideal living conditions "assuming all other factors being equal" therefore we find more insect during the Summer period versus the winter

Wherever you are north or south it is hotter in summer than any other season. Though the timing of summer is different for different places. This is what i could make out of your question.

I believe you are referring to the changes in the seasons.  Because the rotational axis of the earth is tilted a bit more than 23 degrees away from it's orbital plane the earth gets a bit more in the way of the sun (so to speak) as winter approaches so sunrise is a bit later each day, and sunset a bit earlier.  After the winter solstice less and less of the earth is in the way, so sunrise starts a bit earlier each day, and sunset a bit later, until the summer solstice.  Interestingly dusk is longer in the winter because the sun rises and sets at more of an angle to the horizon.  For the same reason, in the tropics dusk is shorter because the sun rises and sets more nearly vertical.  In the more northern part of the northern hemisphere and the more southern part of the southern hemisphere dusk may last all night long in the summer (culminating in the "midnight sun" north of the arctic or south of the antarctic circles).  In addition, due to the refraction of the atmosphere we see the sun earlier than actual sunrise and later than actual sunset (the atmosphere acts as sort of a lens).

The Sun is slightly closer in January at perihelion (147.5 million kilometers) and slightly farther away in July at aphelion (152.6 million kilometers).  Earth’s slightly elliptical orbit is not responsible for our seasons, however.\n\nEarth’s axis is tilted 23.5 degrees with respect to the plane of our orbit around the Sun.  Summer occurs when one’s hemisphere is tilted toward the Sun; winter when it’s tipped away.  Thus, seasons in Australia are reversed relative to North America—summer in Melbourne is winter in New York, and vice-versa.  (I’m sadly aware of that effect, since I’m travelling to Melbourne in a few months.)\n\n\nRyan Wyatt\nRose Center for Earth & Space\nNew York, New York

i totally agree with u! i think ppl are just more randy in the summer! maybe its the heat....

Earth is closest to the Sun in early January (winter for those of us in the Northern Hemisphere, summer for those in the Southern Hemisphere) and farthest in early July.  Distance, however, has absolutely nothing to do with our seasons.  (If it did, the whole world would have the same seasons at the same time.)  Seasons are caused by Earth's tilt.  \n\nAnd NO, summer in the Northern Hemisphere is not caused by the Northern Hemisphere being *closer* to the Sun.  Think about it - if the varying distance of the entire Earth - several million miles - makes no difference in our seasons, how would the varying distance caused solely by our tilt - a few thousand miles - affect anything?  This is a common misconception, but it is wrong.\n\nSeasons are caused by the varying height of the Sun.  In the summer, the Sun gets higher in the sky during the day, heating your area of the Earth more effectively.  In winter, the Sun does not get very high, and so its energy is more spread out, and thus heats less effectively.

I prefer 3 12`s because it gives me a lot more days off in between.

In the summer. It takes a lot more energy to cool the body down, than to heat it up... Something to do with optimal temperatures for enzyme function, blah, blah, blah...

Because in the Summer your body is hot and needs more liquids.  It uses up what it needs and then excretes the extra, through peeing or sweating.  In the Summer you probably sweat more so more of the extra stuff is excreted that way.

Because the air is less dense the higher the altitude, there are less molecules available to retain heat. Therefore the heat of the sun dissipates more readily.
