Which of following statements true concerning bergeron findeisen process It only takes place in clouds with supercooled water droplets ice crystals. The bergeron findeisen process can be summarized as such the air reaches saturation some of resulting droplets will come in contact with freezing nuclei (assuming they have reached activation temperature) we will now have a combination of ice crystals supercooled water droplets from perspective of supercooled droplets air in equilibrium at saturation but from perspective of ice crystals air supersaturated therefore water vapor will sublimate on ice crystals since amount of water vapor in air has decreased from perspective of supercooled water droplet air subsaturated supercooled water will evaporate until air once again reaches saturation the process then continues in short summary ice crystal grows through sublimation at expense of supercooled water droplet. Question 136-27
Which of following statements true concerning coalescence process In mid latitudes this process produces only drizzle or very light rain. cloud droplets are carried air currents within cloud if they bump into each other it called a collision however if they collide then stick together that called coalescence this process important especially in tropics in increasing size of raindrops it falls short of being primary mechanism the formation of raindrops the collision coalescence process of relatively little importance in middle high latitudes where even in summer precipitation begins high in clouds where temperatures are well below freezing the dominant precipitation producing mechanism the so called ice crystal or bergeron process.

Question 136-34
Which of following typical the passage of an active cold front in summer Mainly towering clouds. an active cold front pushing warm moist air up from underneath producing some layered cloud but almost always cumulus cloud turbulent weather when front has passed through air now cold therefore more dense dense air higher pressure.
