Ocean currents moving away from the equator bring warm waters.

No, air is not gravity. Gravity is gravity, and air is air. You can have air without gravity, and you can have gravity without air. On Earth's surface we have both air and gravity.

When lightning appears in the remote distance and appears to produce no thunder sound, it is popularly known as "heat lightning."

Meteorologists will tell you that there really is no such thing as a distinct type of lightning that is not followed by thunder.

All lightning produces thunder, but it is only audible for a distance of some 15-20 miles from the storm. At night, lightning can be seen for distances of up to 125 miles if the conditions are right. So when lightning is seen but no thunder is heard, you are simply too far away from the storm.
