Usually this is a good sign that you will need to replace your HWH soon. If your HWH is 15 - 20 years old, you will realize a savings in your gas bill when it is replaced. When you replace your HWH it is a good time to adjust your water temperature and insulate the pipes (at least the ones that are easily accessible); it will save you considerable money.
Gas water heater has an orifice for main burner and for pilot light, if not electronic ignition.
No.
No water supply
A big enough gust of wind could possibly blow out pilot light, which would cause burner to go off. Unlikely burner to get blown out by wind.
Yes. A solar heater would do that, if there's sun light.
In a gas water heater: The gas flame warms the water, exactly the same way as a gas stove burner does for a pan of water on the stove. In an electric water heater, an element - same as an electric range element, but a different shape - heats up from electrical current, and transfers that heat to the water.
There should be two screws holding the cover on. You will need to disconnect the supply line for the burner and pilot light, the thermocouple and the sparker wire and take the burner out as a unit.

The cold water supply enters the tank at the bottom near the burner. Heat rises, as does hot water. The hot water supply is piped out from the top.
Because of the carbon monoxide produced from the burner at the bottom that would build up and kill you.
Condensation may cause sizzling and popping noises within the burner area during heating periods.
