A NorLun trough is a inverted trough that usually occurs along northeast coast of the United States. It generally extends from the surface up to near 850 or 800 mb. Winds around the trough are convergent and light. This helps to keep the trough in place to produce heavy snow. Another important ingredient for a NorLun trough is to have steep lapse rates in the lower part of the atmosphere...again generally from 800 mb and below.
