Why is the weather not the same, on the same day every year?

Question

What changes, to add the variation?

Answer 1

i think the sun besides man makes the difference. i think solar flares and the different amount of solar energy creates pressure areas that affect wind and storms. also i guess its a cascading affect, the previous days conditions affecting the next day's weather. besides the planet doesn't know about the fact that we have years and days. thats just an invention of man to make things more organized.

Answer 2

Simple. It is a matter of pure statistics. For the weather to be the same on ANY day, a truly gigantic set of seperate things need to be identical. e.g Pressure at X height, pressure gradients, temperature at X height, temperature gradient plus many thousands more (such as the number of butterflys out an about on that particular day) ....and all of these in 4 dimensions! (Because how they vary in time is critical too)
Therefore, even though some very simple conditions, such as where we are in relation to the sun (night/day, summer/winter etc) are the same each year, it is inconceivable that the many other factors will be similar, so the weather is very, very unlikely to be "the same".

Answer 3

It has to do with groundhog day. If the groundhog sees his shadow, then the weather for the next year will be exactly the same on each day as the preceeding year. If the groundhog does not see his shadow, then you get a new year of different weather. This was scientifically proven by Einstein and Madonna.

Answer 4

It likely would be if the jet stream flowed in a river bed. However the jet stream is free to meander and that causes huge air masses to flow in different directions on the same day of the year. Our weather often depends upon whether an air mass is arriving from the Gulf or from Canada.

Answer 5

It might appear a silly question but whilst day to day weather patterns year on year are rarely the same if you study seasons and monthly patterns generally they do not change. That's how seasons were defined.

However, this year has to be the exception to that rule and anyway if you live in Scotland your privvy to four seasons in one day.

So no the weather is rarely the same on the same day each year...but wait how was St Swithins day defined..'If it rains on the 15th July it is said to rain for forty days and forty nights'

Something to be said for folklore!

Answer 6

Sometimes weather r the same... Lik there can be a few sunny days then follo by rainy days... Why? Casue when it's sunny... Water evaporate, goes to sky, form clouds, clouds get heavy and rain and blah blah blah...

But other occasion, there is drastic weather changes cause well... Global warming and etc...

Answer 7

Weather is like a tornado, lightning, and snow flakes, they are never the same all the time, each day is different, depending on the pattern it is each day.

Answer 8

Its the same every January 3. Wet and cold ! My birthday

Answer 9

they are nonetheless very youthful. i could do away with the paper. shop them interior the kennel once you're no longer living house. And take them outdoors as frequently as conceivable once you're living house. With consistency, maximum domestic dogs are potties experienced around 4-5 months previous.

Answer 10
