The Butterfly Effect

The Butterfly Effect; Noun; a term attributed to Edward Lorenz and used to describe the effect a small disturbance can have on a non-linear dynamical system (the atmosphere for example). Also called “sensitivity to initial conditions”, it refers to the idea that the tiny perturbations in the atmosphere caused by the flap of a butterfly’s wings can ultimately set off a tornado or other high powered storm (conversely, it can also prevent such an event).

I was reminded of this phenomenon when Karen and I took a walk down the Auto Road to check on one of the Auto Road Vertical Temperature Profile (ARVTP) sites. Frozen to the road was a monarch butterfly. And who knows, had it not succumbed on the side of Mt Washington it may have been the instrumental force in preventing the yesterday’s storm.
