Do ice crystals form in running super-cold water?
Earth ScienceAsked by: Ellen Belanger At what temperature do ice crystals form? Fig. 1. At temperatures above 0°C, water remains a liquid. Between 0 and about -36°C, water only crystallises into ice if coerced e.g. by making freezing more likely by there being an ice nucleus, such as a dust particle, present in the water. How
What factors determine the number of Hadley cells for a planet?
Earth ScienceAsked by: Philip Page So the number of cells will be determined by the winds that start either at the equator or the pole and the distance that they can cover before being deflected into completely zonal direction. What are global atmospheric circulation cells made of? The global circulation can be described as the world-wide
Does the snow come from local moisture or transported moisture?
Earth ScienceAsked by: Philip Page The moisture comes from nearby water bodies, and then it’s transported to where it’s going to precipitate. It is local and transported moisture. Is there moisture in snow? Liquid equivalent is the amount of measurable moisture if the snow were to have fallen as rain. This is where the infamous “10-to-1”
Why does the earliest sunset time not coincide with the shortest day of the year?
Earth ScienceAsked by: Quintin Prestige It changes throughout the year because the earth’s axis is tilted with respect to its orbit around the sun, and the earth’s orbit is an ellipse. The longer-than-average solar day around the solstices causes both earliest sunset and latest sunrise to not fall on the solstice. What is the earliest sunset
Is there a list of instances where mountains that have been mined out of existence?
Human ImpactAsked by: Quintin Prestige What is the oldest mine in the world? The Ngwenya Mine The Ngwenya Mine is located on Bomvu Ridge, northwest of Mbabane and near the northwestern border of Eswatini (Swaziland). This mine is considered to be the world’s oldest. What is mining in geography? Mining is the process of extracting useful
What is the difference between w-wind, vertical p-velocity and Omega?
Earth ScienceAsked by: Tracey White What is omega vertical velocity? Omega is the vertical velocity in pressure coordinates (so positive omega is negative w). Omega has units of pressure per time. Because much of the operational meteorology uses pressure surfaces, omega is a more common quantity to see. What is omega in wind? Contact Us. T-Omega
