Where is the least polluted place to live on earth?
Earth scienceAsked by: Kira Huntington The world’s least polluted countries are a mixture between countries and island countries, with the top three being Cape Verde, the Caribbean Netherlands (Bonaire, Sint Eustatius and Saba) and Finland. What place on Earth has the least pollution? 1. Zurich, Switzerland (0.51µg/m3) Zurich is the least polluted city in 2021 and

Estimating Average Rainfall
Earth scienceAsked by: Kira Huntington The grid point precipitation value is calculated based on the sum of the individual station weight multiplied by observed station value. Once the grid points have all been estimated they are summed and the sum is divided by the number of grid points to obtain the areal average precipitation. How do

Direct and Diffused component of shortwave radiation in ERA5 data
Earth scienceAsked by: Richard Hernandez What is diffuse shortwave radiation? Shortwave solar radiation can be separated into two components: direct and diffuse beam. Diffuse beam is the portion of the radiation that has been scattered by gas molecules and suspended particles in the atmosphere and reaches the earth’s surface from multiple directions. What are the types

Is sea erosion the opposite of sea level rising (or rather, an adjacent phenomenon)?
Earth scienceAsked by: Richard Hernandez Sea erosion is not the opposite of sea level rising, it is a direct consequence of it. How does sea level rise effect erosion? Sea level rise can also increase coastal erosion because waves can extend further up and along beaches and cliffs. Erosion is happening faster along coastlines made from

Is there any possible way that a tropical cyclone of any strength could form over land?
Earth scienceAsked by: Joseph Salleh Would it be possible for a tropical cyclone to form over land? Because tropical cyclones need warm water to survive, the chances of tropical cyclone formation happening over dry land are slim. Only 2 percent of all Atlantic tropical cyclones have formed over land (1851-2015), according to Michael Lowry, hurricane specialist

What is the difference between roughness length and zero plane displacement?
Earth scienceAsked by: Joseph Salleh What is zero plane displacement? A height scale in turbulent flow over tall roughness elements associated with the average level of action of momentum transfer between the flow and the roughness elements. What is surface roughness length? A measure of the amount of mechanical mixing introduced by the surface roughness elements

Why does wind direction change in a front?
Earth scienceAsked by: Jeff Buford Do fronts change wind direction? A sudden change in wind direction is commonly observed with the passage of a warm front. Before the front arrives, winds ahead of the front (in the cooler air mass) are typically from the east, but once the front passes through, winds usually shift around to

How do the various types of clouds affect the atmosphere below them in a polluted environment?
Earth scienceAsked by: Christian Williams How does air pollution affect the clouds? In moderate concentrations, they add more particles to the atmosphere for water to condense onto, enabling clouds to grow taller. If pollution is very heavy, however, the sheer number of particles in the sky blocks incoming sunlight — an effect often visible in the

How does metamorphism change talc into soapstone?
Earth scienceAsked by: Christine Harris How is soapstone formed? Soapstone is formed by the metamorphism of ultramafic protoliths (e.g. dunite or serpentinite) and the metasomatism of siliceous dolomites. By mass, “pure” steatite is roughly 63.37% silica, 31.88% magnesia, and 4.74% water. It commonly contains minor quantities of other oxides such as CaO or Al2O3. What does
