How does wind form - 0 views

  • All winds are caused by differences in air pressure, which are usually caused by the sun. When high air pressure flow into low air pressure, it creates wind.Our planet turns around the Sun on an axis with a 23 degree tilt towards the North Star. The difference of heating on the surface of the Earth (between the equator and the pole) causes a mass of hot air to go up and to displace colder air toward the bottom - this all causes movement in the mass of air that is contain in our atmosphere.

  • Types of soot include: Wet Smoke Residues - Result from smoldering fires with low heat. Residues are sticky, smeary and with pungent odors.  Smoke webs can be difficult to clean. Dry Smoke Residues - Result from fast burning fires at high temperatures. Residues are often dry, powdery, small, nonsmeary smoke particles. Protein Residues - Virtually invisible residues that discolor paints and varnishes.  Extreme pungent odor. Fuel Oil Soot - Furnace puff backs distribute fuel oil soot. Other Types of Residues - Tear gas, fingerprint powder, and fire extinguisher residues also need cleanup.

  • Wind is the flow of gases on a large scale. On Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in our solar system occur on Neptune and Saturn.
  • Winds can shape landforms, via a variety of aeolian processes such as the formation of fertile soils, such as loess, and by erosion. Dust from large deserts can be moved great distances from its source region by the prevailing winds; winds that are accelerated by rough topography and associated with dust outbreaks have been assigned regional names in various parts of the world because of their significant effects on those regions. Wind affects the spread of wildfires. Winds disperse seeds from various plants, enabling the survival and dispersal of those plant species, as well as flying insect populations. When combined with cold temperatures, wind has a negative impact on livestock. Wind affects animals' food stores, as well as their hunting and defensive strategies.
  • Wind is caused by differences in pressure. When a difference in pressure exists, the air is accelerated from higher to lower pressure. On a rotating planet, the air will be deflected by the Coriolis effect, except exactly on the equator. Globally, the two major driving factors of large-scale winds (the atmospheric circulation) are the differential heating between the equator and the poles (difference in absorption of solar energy leading to buoyancy forces) and the rotation of the planet. Outside the tropics and aloft from frictional effects of the surface, the large-scale winds tend to approach geostrophic balance. Near the Earth's surface, friction causes the wind to be slower than it would be otherwise. Surface friction also causes winds to blow more inward into low pressure areas.
