What is a characteristic phenomenon for a stable atmosphere ?
The name of the phenomenon that describes very large variations in wind speed which can sometimes be caused by a line of thunderstorms is ?
Thermal ascents are created Surface heating, strong wind, high humidity, low amount of sunshine. 
Best conditions the establishment of a land breeze are At night, clear to little cloudy sky, at day, clear to little cloudy sky, at day, overcast ceiling, at night, overcast ceiling. 
The curves or lines that connect points of equal pressure are called Isobars, isoclines, isothermals, isogrids. 
Convective activity of atmosphere usually result in Some turbulence, the formation of stable clouds, some rain, a reduced visibility. Question Section 4: Meteorology 21 Answer 8
Lenticular clouds are usually associated with A mountain wave, a temperature inversion, a quasi stationary front, an occluded front. Question Section 4: Meteorology 21 Answer 9
The dangerous phenomena associated with cumulonimbus cb are 1 hail2 turbulence3 wind shear4 lightning5 fogchoose most complete exact combination , 2, 3, 4,, 2, 3, 5, 4. Question Section 4: Meteorology 21 Answer 10
Winds generated cumulonimbus associated with thunderstorms are dangerous because they are 1 highly irregular in direction2 highly irregular in speed3 laminar4 responsible wind shear5 generators of strong gusts6 highly regular in speed , 2, 4 5, 3, 4, 5 6, 2, 3, 4 5,, 4, 5 6. Question Section 4: Meteorology 21 Answer 11
When mist reported visibility Between km 5 km, aboutkm, not affected this phenomenon, below km. Question Section 4: Meteorology 21 Answer 12
When wind arrives over land wind speed Decreases, increases, decreases only above friction layer, decreases linearly. Question Section 4: Meteorology 21 Answer 13
When wind arrives on ground it Slows down, accelerates, rises, fades. Question Section 4: Meteorology 21 Answer 14
Clouds which cloud type indicates presence of significant vertical currents at low levels Cumulus, stratus fractus, altocumulus, nimbostratus. Question Section 4: Meteorology 21 Answer 15
Among following clouds one most likely to produce hail the Cumulonimbus, stratus, cirrus, altocumulus.
