If it was on the ground it wouldn't be fog it would be water.  The sky begins immediately above the ground.  So fog is in the sky.

A QUARTER of an hour ago\nI saw the most heavenly show\nThe night was FULL and all aglow\nThe WAXING CRESCENT stood tall and alive\nTrying is best not to WANE that is to what it would strive\nBut the GIBBOUS stood,  WAXING OR WANING\nAnd new that the CRESCENT was futily straining\nBecause the stars were watching with NEW facination\nAs the men missed this site because of their jubilation\nThey were engrossed from the FIRST to the LAST QUARTER of watching their favorite sport station

I was fox hunting with my ex wife's uncle one night. It was a clear sky and stars everywhere. We were walking through a meadowfield and all of a sudden everything lit up around us like it was daylight. As quick as it happened it was over. We looked at each other startled and still to this day don't have answers. There was no noise and nothing in the sky.

Apparently but one person explained that a magical mist rose from the ground which helped things to grow.  Makes perfect sense now.

She is saying that her soul is like a caged bird that cannot fly out into the blue skies. She is trying to describe her inner-most intimate feeling by using a technique called analogy. The bird is analogous to her soul. So if the bird can fly - so does her soul.

Your last question"Why atmosphere is more cozy in cloudy day comparatively other clear days?"\n\nBecause your grammar is so bad no one new what you were asking.

As air rises to get over the mountain, it cools.  Cooler air can't carry as much water vapor as warmer air, so cloud droplets form.

The Innocence\nLooking to the sea, it is a line\nof unbroken mountains.\n\nIt is the sky.\nIt is the ground. There\nwe live it, on it.\n\nIt is a mist\nnow tangent to another\nquiet. Here the leaves\ncome, there\nis the rock in evidence\n\nor evidence.\nWhat I come to do\nis partial, partially kept.

"there were two roads in the forest. i chose the one less traveled and that has made all the difference." \n\ni don't exactly remember who said this and the 'exact words' but this is very close. and i think this very well sums up the answer to your question.

For the most part the wind will blow the fog away.   However here in the Mohawk Valley, I have seen windy fog.

The outward and visible sign of an inward fear.\n\nHe saw a ghost.\nIt occupied — that dismal thing! —\nThe path that he was following.\nBefore he'd time to stop and fly,\nAn earthquake trifled with the eye\nThat saw a ghost.\nHe fell as fall the early good;\nUnmoved that awful vision stood.\nThe stars that danced before his ken\nHe wildly brushed away, and then\nHe saw a post.\n—Jared Macphester\n\nAccounting for the uncommon behavior of ghosts, Heine mentions somebody's ingenious theory to the effect that they are as much afraid of us as we of them. Not quite, if I may judge from such tables of comparative speed as I am able to compile from memories of my own experience.\n\nThere is one insuperable obstacle to a belief in ghosts. A ghost never comes naked: he appears either in a winding-sheet or "in his habit as he lived." To believe in him, then, is to believe that not only have the dead the power to make themselves visible after there is nothing left of them, but that the same power inheres in textile fabrics. Supposing the products of the loom to have this ability, what object would they have in exercising it? And why does not the apparition of a suit of clothes sometimes walk abroad without a ghost in it? These be riddles of significance. They reach away down and get a convulsive grip on the very tap-root of this flourishing faith.

I suspect that what you mean is that the relative humidity is sometimes greater at night than it is during the daytime. This is because the air is warmer usually during the day, so it can hold more moisture.

So, what's the problem?  Do you not know the meanings?  A similie uses like or as.  The sky is like an ocean of air.  A metaphor compares without like or as.  The sky is the ocean of air. alliteration is using the same consonant or vowel repeatedly.  Peter piper picked a peck of pickled peppers.  Personification is like what is going on in Beauty and the Beast.  A bunch of non human things have human qualities.  Imagery uses the five senses.  I hungered for life, ate with my eyes as my plate was filled with food, but in the end, I was overly satisfied and became ill.  My life required peace I didn't know.
