why is the weaether not exactly the same on the same day but diffrent year?

Question

i mean should'nt the weather be like a perfect cycle?

cycle is a wrong word. if the weather is determined by the distance betwean the earth nd the sun shouldnt be exactly the same 365 days ago?

Answer 1

It's not only the distance from the sun nor the axial tilt, nor ANY of the physical characteristics of the planet that determine weather patterns. Temperature, humidity, and pressure all play very important roles, and the very air constantly changes, with man-made factors having some high influence. Rainforests that were there last year may have been cut down. Mountains that before held lots of snow may have leveled a bit and not held so much. Ice caps and glaciers have melted a little more, contributing to higher global humidity and temperature, which can cause more storm systems to develop, sometimes in different areas. Air currents change on scales other than yearly. Storms that form are not always the same size because of constant variants in pressure and wind speed. See why it's so difficult to predict the weather even with the modern instruments of today?

Also, even if your theory were true and perfect weather cycled year-round, remember that the Gregorian calendar we use is far from perfect. The earth does not take 365 days to make an orbit, it takes more like 365 days, 5 hours and 49 minutes. That's why we have the weird leap year schedule, with leap year being skipped every 400 years, and it's still not perfect. So even if the weather formed a "perfect" cycle every 365 days as you suggested, there would still be years when it wouldn't be quite accurate.

Answer 2

No, why should it be?

You are confusing climate with weather.

Earth is orbiting the Sun, as we all know. But it also has changes in its patterns or orbit such as changes in the shape of the orbit and changes in the axial tilt. These can affect seasons/climate on the large scale.

Small fluctuations in local weather patterns affect the daily weather. Just because it might have rained today doesn't mean it will rain Nov. 29 2008.

Answer 3

weather is largely attributed due to solar flares from the sun and different storm systems and air currents and water currents which there will be a medium in which the weather is averaged to be but with global warming who knows.

Answer 4

You're kidding, right? How is the weather supposed to know what day it is, or what it did last year?

Do clouds know how to read calenders?
