What would be the most likely direction of the surface winds at the x, assuming typical values of surface friction? (Assume northern hemisphere) - From the west. The figure above shows five environmental lapse rates (ELRs). What would happen to an air parcel forced to rise from the surface in an atmosphere represented by ELR 3 (yellow line)? - it would continue rising The below picture depicts a field of wind observations in the northern hemisphere. Overlaid on the wind observations are four cold fronts, only one of which is correct. Based on the winds alone, which front is most correct? - D The following weather conditions were observed at location A: - Snow at 00Z - Sleet at 03Z - Freezing rain at 06Z - Rain at 09Z - Clearing skies at 12Z The wind direction at 00Z was NE. The wind direction at 12Z was S. 2COPYRIGHT © 2025 BY BRITTIE DONALD, ALL RIGHTS RESERVED What feature likely passed location A during this time period? - warm front The polar jet tends to lie directly above regions of with - strong temperature contrast. The atmosphere is typically most unstable _____. - during the mid/late afternoon CAPE is defined as the area where the air parcel is warmer the environment between the _______ and the _______ . - LFC; EL A saturated parcel in a conditionally unstable layer is _____. - unstable At which level does an air parcel begin to rise due to buoyancy alone? - level of free convection The moist adiabatic lapse rate is most differentthan the dry adiabatic lapse rate _____. - at warm temperatures (i.e., > 20C) The standard environmental lapse rate is __________ . - cond
