A saturated parcel in a conditionally unstable layer is . - CORRECT ANSWERunstable Above the boundary layer in the northern hemisphere, when the winds are to your back, low pressure would be: - CORRECT ANSWER-to your left An unknown front (dark black line) is shown above moving in the direction of the arrow. Just to the east of the front the 1000-850mb thickness is 1330 meters (dashed line) while just to the west, the 1000-850mb thickness is 1270 meters (dashed line). What type of front is it? (Hint: Consider the relationship between thickness and the average temperature of the layer) - CORRECT ANSWER-Warm front with warm air replacing cold air. As unsaturated air parcels rise, they cool at the . - CORRECT ANSWER- dry adiabatic lapse rate At which level does an air parcel begin to rise due to buoyancy alone? - CORRECT ANSWER-Ievel of free convection CAPE is defined as the area where the air parcel is warmer the environment between the and the . - CORRECT ANSWER-LFC; EL For a mid-latitude cyclone to intensify (lower in pressure), there must be in the upper levels (i.e., above the 500 mb level) directly overhead the suGfÅöiü¯ pressure center. - CORRECT ANSWER-divergence Given the above mean sea-level pressure surface chart with isobars drawn and labeled. What would be the most likely direction of the surface winds at the x, assuming typical values of surface friction? (Assume northern hemisphere) - CORRECT ANSWER-From the west. If the environmental lapse rate is greater than the moist adiabatic lapse rate and less than the dry adiabatic lapse rate, the layer is- CORRECT ANSWERconditionally unstable
