Heinrich-type events in a low-order dynamical model of global climatic change / M. Verbitsky, Barry Saltzman.

Title: Heinrich-type events in a low-order dynamical model of global climatic change / M. Verbitsky, Barry Saltzman.
Author(s): Verbitsky, M.
Saltzman, Barry.
Date: 1993.
In: Eos : transactions, American Geophysical Union. (1993.), Vol. 74(43, supplement) (1993)
Abstract: Abstract. Recent studies suggest occurrence of sporadic episodes during which ice streams that discharge ice sheets become very active, producing large amounts of icebergs, reflected in North Atlantic sea cores as Heinrich events. To simulate this, in context of general palaeoclimatic model, sliding catastrophe function is introduced that can account for ice-sheet surges. Function is expressed in terms of thickness and physical properties of ice. Analysis suggests that Heinrich-type events might be of three possible kinds; these are discussed.
