A: Flowering of onions can be caused by several things, usually temperature fluctuation. An onion is classed as a biennial which means it usually takes two years to go from seed to seed. However, this condition is triggered by temperatures.
Under what conditions will the front of a glacier remain stationary? Glacial fronts remain stationary when melting and snow accumulation are equal. Glacial fronts remain stationary when friction exceeds gravity forces. Glacial fronts remain stationary when melting and snow accumulation are unequal. Glacial fronts remain stationary when gravity forces exceed friction.
Indicators of a approaching warm front are: high cirrus clouds followed by a lowering base of Cirri-, Alto-and Nimbostratus clouds. Flying into a warm front you may notice lower stratiform clouds, ice pellets (depends on freezing level), freezing rain and rain.
