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

Rainfall units conversion from depth to rate/intensity
Earth ScienceAsked by: Tracey White In order to have the average rainfall intensity in m/s corresponding to that interval of time, you have to divide the rainfall depth for the number of seconds in the time interval or for mm/s you multiply for 1000/21600. If you want the intensity in m/h you divide for 6 hours.

Why does the moon orbit the earth and not the sun instead?
Earth ScienceAsked by: Lynn Logan The force of the gravitational force of earth is more than the sun on moon.So the moon revolves around the earth not the sun. Why does the moon orbit the earth instead of the earth orbiting the moon? Earth is larger than the moon, so Earth pulls on the moon. At

How does the lack of data about the Mesosphere affect our predictive knowledge of the atmosphere?
Earth ScienceAsked by: Lynn Logan Why do we know so little about the mesosphere? The mesosphere is difficult to study, so less is known about this layer of the atmosphere than other layers. Weather balloons and other aircraft cannot fly high enough to reach the mesosphere. Satellites orbit above the mesosphere and cannot directly measure the

Publicly available data set with ensemble forecasts and observations?
Earth ScienceAsked by: Robby Filippi Why do we use ensemble forecasts? Ensemble forecasting is a method used in or within numerical weather prediction. Instead of making a single forecast of the most likely weather, a set (or ensemble) of forecasts is produced. This set of forecasts aims to give an indication of the range of possible

What are the reaction mechanisms for singlet oxygen in the atmosphere?
Earth ScienceAsked by: Robby Filippi What process produces singlet oxygen? photosensitization In solution, the singlet oxygen is often prepared by a process called photosensitization. A photosensitizer is irradiated to its singlet excited state, followed by conversion (called intersystem crossing) to its triplet excited state. Why is singlet oxygen so reactive? Because of differences in their electron
