Altimeters work based on the principle that for every 10 meters in altitude you gain, the air pressure decreases by roughly 1 millibar. If you fly over an area of warmer air, the relative air pressure at your current altitude will be higher than it was while you were over the cooler air.. The atmosphere also tends to expand when surface and air temperatures are. You would read the total altitude as 10,000+2,000+660=12,660. The altimeter is therefore under-reading the true altitude.
