I've been a broadcast meteorologist on television since the early 1990's. Happy to answer any questions about the weather or local TV news. Yes, I often wear sneakers on set just out of view of the camera.
Great question, Marv! The exact location would have a lot to do with it but, in general, cold air is heavier than warm air. In the winter, especially at night, the cold air sinks into the valleys and pools up. At the beach, when the sun is out, the land warms faster than the water and the air above the land rises. Since the air needs to be replaced the cooler air moves in from over the water on the sea breeze. Hope that helps. Thanks!

You might get a better answer from a hydrologist, Glen. Water does continue to empty into the ocean, or a lake. The overflow occurs when the water running into the river is greater than what is flowing out. The incoming water can come from creeks and streams and heavy rain. Thanks!

Yup. Some do. ;)

Often times changes like that come because the outlook on a given day is highly dependent on what happens during the day or days before. A small variation in the specific way storms develop and behave can mean a big change in the development hours later or the next day. Another explanation includes the somewhat large distance between twice daily weather balloons. A lot of things can go undetected between them. Thanks, DJ!

For the most part the sun doesn't directly heat the air. It heats the ground which then reradiates that energy in the form of longer wave radiation which heats the air. The strongest heating occurs midday when the sun is highest in the sky. At that point the sunlight is traveling through the least amount of atmosphere as opposed to earlier or later in the day. So there is a short lag between maximum sun angle and the time is takes the air to heat up. Thanks, Tommy. Hope that makes sense.

Really haven't researched much so no opinion.

Hi, Darinesha. Not sure exactly what you are asking. If you mean the gases that make up the atmosphere you might do a web search. The two highest concentrations are nitrogen and oxygen and a list of other things including water vapor. Thanks!
