well, the words all seem to refer to weather and nature, so I presume it refers to temperature rather than police... and, come to think of it, there is at least one very bad rhyme in there - "clouds" and "sound"... it's from A HORSE WITH NO NAME

On the first part of the journey
I was looking at all the life
There were plants and birds and rocks and things
There was sand and hills and rings
The first thing I met was a fly with a buzz
And the sky with no clouds
The heat was hot and the ground was dry
But the air was full of sound
