WEATHER CHANNEL: This close up shows a thunderstorm's 'overshooting top', which signifies the strongest updrafts within the thunderstorm. These tops can easily reach heights greater than 39,000 feet. The gauzy feature around the overshooting top is the cirrostratus cloud deck that forms the thunderstorm's signature 'anvil.' Surface temperatures of the nearby Pacific Ocean remain chilly year round - in the mid-50s. In contrast, the California landmass is often much warmer. Onshore flow sets up, and as air moves over the Pacific toward land, water vapor within it cools, condenses, and forms a dense deck of fog.
