Know which force causes wind. - CORRECT ANSWER-Coriolis Force and friction. - Know the necessary ingredients for thunderstorm development. - CORRECT ANSWER-Moisture, Instability, and. a lifting action - Know which atmospheric factor helps determine whether thunderstorms will become severe - CORRECT ANSWER-Moisture - Know some examples of thunderstorm triggers/lifting mechanisms. - CORRECT ANSWER-Iow level convergence, low level WAA, low level moisture advection, mesoscale convergence boundaries such as outflow and sea breeze boundaries, orographic upslope, frictional convergence, vorticity, and jet streak. - Know at what outside temperature range aircraft lightning strikes are most likely to CORRECT ANSWER-near freezing temperatures. - Know how to identify thunderstorm structural types (supercell, squall line,mesoscale convective complex, etc.) on radar. - CORRECT ANSWER-Mesoscale convective complex (MCC)—A particular type of MCS, an MCC is a large, circular, long-lived cluster of showers and thunderstorms identified by satellite. A squall line is a group of storms arranged in a line, often accompanied by "squalls" of high wind and heavy rain. A supercell is a long-lived (greater than I hour) and highly organized storm feeding off an updraft Typicallyfoundinthemidwest - Know what particles are reflecting radiation back to the radar. - CORRECT ANSWERelectromagnetic waves or radiation - Know the difference between base and composite reflectivity and which is most CORRECT ANSWER-Composite reflectivity displays the highest reflectivity of ALL elevations scans. Base reflectivity only shows reflected energy at a single elevation scan of the radar. - Know the difference between
