There were about 1, firefighters on the lines. The name of the firefighter killed in the nearby El Dorado Fire was being withheld until family members are notified. No other information was released about the firefighter, the agency the firefighter worked for, or the circumstances of the death.

The body was escorted down the mountain in a procession of first-responder vehicles. Get all the stories you need-to-know from the most powerful name in news delivered first thing every morning to your inbox.

Breonna Taylor unrest: Seattle officer struck in head with baseball bat; police arrest There are also strong evolutionary constraints on this dispersal mechanism.

For instance, species in the Asteraceae on islands tended to have reduced dispersal capabilities i. Unusual mechanisms of wind dispersal include tumbleweeds.

A related process to anemochory is anemophily , which is the process where pollen is distributed by wind. Large families of plants are pollinated in this manner, which is favored when individuals of the dominant plant species are spaced closely together. Wind also limits tree growth. On coasts and isolated mountains, the tree line is often much lower than in corresponding altitudes inland and in larger, more complex mountain systems, because strong winds reduce tree growth.

High winds scour away thin soils through erosion, [] as well as damage limbs and twigs. When high winds knock down or uproot trees, the process is known as windthrow.

Wind can also cause plants damage through sand abrasion. Such windblown sand causes extensive damage to plant seedlings because it ruptures plant cells, making them vulnerable to evaporation and drought. Using a mechanical sandblaster in a laboratory setting, scientists affiliated with the Agricultural Research Service studied the effects of windblown sand abrasion on cotton seedlings.

The study showed that the seedlings responded to the damage created by the windblown sand abrasion by shifting energy from stem and root growth to the growth and repair of the damaged stems. Pikas use a wall of pebbles to store dry plants and grasses for the winter in order to protect the food from being blown away. Their cerci are very sensitive to the wind, and help them survive half of their attacks. Wind causes the generation of sound.

The movement of air causes movements of parts of natural objects, such as leaves or grass. These objects will produce sound if they touch each other. Even a soft wind will cause a low level of environmental noise.

If the wind is blowing harder, it may produce howling sounds of varying frequencies. This may be caused by the wind blowing over cavities, or by vortices created in the air downstream of an object.

Examples of these parts are balconies, ventilation openings, roof openings or cables. High winds are known to cause damage, depending upon the magnitude of their velocity and pressure differential.

Wind pressures are positive on the windward side of a structure and negative on the leeward side. Infrequent wind gusts can cause poorly designed suspension bridges to sway. When wind gusts are at a similar frequency to the swaying of the bridge, the bridge can be destroyed more easily, such as what occurred with the Tacoma Narrows Bridge in Winds of this strength due to downsloped winds off terrain have been known to shatter windows and sandblast paint from cars.

The Saffir—Simpson scale and Enhanced Fujita scale were designed to help estimate wind speed from the damage caused by high winds related to tropical cyclones and tornadoes , and vice versa. The blast wave is similar to a strong wind gust over the ground.

Wildfire intensity increases during daytime hours. For example, burn rates of smoldering logs are up to five times greater during the day because of lower humidity, increased temperatures, and increased wind speeds.

Wildfires are fanned by these winds and often follow the air currents over hills and through valleys. The solar wind is quite different from a terrestrial wind, in that its origin is the sun, and it is composed of charged particles that have escaped the sun's atmosphere. Similar to the solar wind, the planetary wind is composed of light gases that escape planetary atmospheres. Over long periods of time, the planetary wind can radically change the composition of planetary atmospheres.

The fastest wind ever recorded is coming from the accretion disc of the IGR J black hole. The hydrodynamic wind within the upper portion of a planet's atmosphere allows light chemical elements such as hydrogen to move up to the exobase , the lower limit of the exosphere , where the gases can then reach escape velocity , entering outer space without impacting other particles of gas.

This type of gas loss from a planet into space is known as planetary wind. It consists mostly of electrons and protons with energies of about 1 keV.

The stream of particles varies in temperature and speed with the passage of time. These particles are able to escape the sun's gravity , in part because of the high temperature of the corona , [] but also because of high kinetic energy that particles gain through a process that is not well understood.

The solar wind creates the Heliosphere , a vast bubble in the interstellar medium surrounding the Solar System. From Wikipedia, the free encyclopedia. For other uses, see Wind disambiguation.
