Back-sheared anvil – updraft strength vs. wind shear

back-sheared anvil

A back-sheared anvil is the expression for a cumulonimbus anvil that spreads against (upwind) into relatively strong winds (jet stream) aloft. Anvil vs. wind As the anvil is forming, it is under the influence of upper-level winds. Typically as you go higher in the troposphere, winds increase. Under stable conditions with high pressure, winds in … Read more
