How does the lapse rate in clouds compare with the lapse rate of air?
Earth ScienceAsked by: Carrie Bendinger How does the lapse rate typically compare between the inside and outside of a cloud? The lapse rate of temperature is ignorant of clouds, it only cares that either e/es=1 (moist), where e is vapor pressure and es is saturation vapor pressure. A cloud is saturated (and in places supersaturated) and

What does the precessional parameter measure?
Earth ScienceAsked by: Tim Lakemary What is the precession index? The precession index is e sin omega(sub s) where e is the Earth’s orbital eccentricity and omega(sub s) measures how close the Sun is to the Earth at midsummer. When omega(sub s) = 90deg the Sun is close to the Earth during northern summer, and at

Equations for Global Temperature Models
Earth ScienceAsked by: Tim Lakemary How is global temp calculated? To calculate global temperature, researchers average the readings for each grid point, weighted by the area associated with that grid point. Latitudes further away from the equator have smaller areas. What is the fundamental equation on which climate models are based? The most important of these

Specific humidity range in tropical lowlands?
Earth ScienceAsked by: Rudy Wall What is the range of specific humidity? According to Ahrens (2007), the average specific humidity ranges from 0.004 kg/kg at 60 degrees (north or south) to 0.018 kg/kg at the equator. Since these are only average values, it is possible to have higher or lower values depending on the specific environmental

What actually happens to reduce the perceived color in a ‘white rainbow” or “fog-bow”?
Earth ScienceAsked by: Rudy Wall Why are fog bows white? The droplets’ small size is the reason fog bows are pure white. Rainbows form when light enters raindrops and gets diffracted and scattered in a very organized manner, which separates it into the colors of the visible spectrum. Fog drops are too small to achieve this.

Does snow melt on ice?
Earth ScienceAsked by: Joshua Love Snow will not cause the ice to melt……… however if there is over say 6 or more inches of snow on the ice it will somewhat insulate the ice causing it to not thicken as quick as if it was bare ice……..will still make ice but just at a slightly slower
