While most severe wind events tend to be related to strong pressure gradients given the synoptic forcing common during the cool season as related to intensifying low pressure systems and strong frontal boundaries; damaging wind events associated with convective systems also do take place. Measure pressure gradients across heart valves to help assess valve disease. Measurement of renal artery pressure gradients may hold some promise in this regard. |
