Which boundary shift occurs with increased high-latitude ice sheet formation?

💡 Explanation

A growing ice albedo cools high latitudes, because this induces subsidence. This strengthens the polar high and compresses the Hadley cell via thermal forcing; the Hadley cell edge migrates equatorward therefore, rather than other cell expansions from jet stream instabilities.
