Now let’s look at a slightly different image of hurricanes. This one illustrates that the way hurricanes form depends, in part, on how warm the surface of the ocean is. In this image, warmer water is indicated by reds and yellows; colder water appears blue. Where do you see the hurricanes developing? [Pause/allow for answers.] Hurricanes form in warm water, where it appears red. They typically need ocean surface temperatures of over 79° Fahrenheit to form.
Offering explicit cues to orient to new images helps visitors track the narrative more effectively.
This “beat” in the narrative is the pivot point to climate change, as it introduces the topic of temperature increase.
IMAGE: 2005 hurricanes and sea surface temperature. Watch the time stamp to identify the time period for this data set. Wait to point out Katrina (8/24–8/30). Rita and Wilma were other memorable events that season.
