Therefore, windbreaks (such as big trees and bushes) are often planted by farmers to reduce the wind erosion of loess. Wind pressures are positive on the windward side of a structure and negative on the leeward side. This is most likely on windward slopes of mountains, with severe cases generally occurring to tree stands that are 75 years or older. 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. When dust from the Sahara moving around the southern periphery of the ridge within the belt of trade winds moves over land, rainfall is suppressed and the sky changes from a blue to a white appearance, which leads to an increase in red sunsets. The Harmattan carries dust during the winter into the Gulf of Guinea. The Calima carries dust on southeast winds into the Canary islands.

I grew a few dust bunnies. The Sirocco brings dust from north Africa into southern Europe because of the movement of extratropical cyclones through the Mediterranean. During mid-summer (July in the northern hemisphere), the westward-moving trade winds south of the northward-moving subtropical ridge expand northwestward from the Caribbean into southeastern North America. Similar dust plumes originate in the Gobi Desert, which combined with pollutants, spread large distances downwind, or eastward, into North America. There is a large variability in the dust transport to the Caribbean and בוט טלגראס - telegrass2u.com - Florida from year to year. There are also strong evolutionary constraints on this dispersal mechanism. Humans are unable to prevent or even slow down wind dispersal of plant pathogens, requiring prediction and amelioration instead. Vegetables: Pick out your favorite vegetables to plant in next year's garden. A variety of your favorite vegetables, herbs, flowers and other plants will grow in containers. Strong winds will pick up loose sand and topsoil and hurl it through the air at speeds ranging from 25 miles per hour (40 km/h) to 40 miles per hour (64 km/h).

Sunlight warms the ground during the day and causes air currents to travel uphill, and downhill during the night as the land cools. Wildfires are fanned by these winds and often follow the air currents over hills and through valleys. Westerly winds in the mid-latitudes of the planet drive the movement of ocean currents from west to east across the world's oceans. Total destruction to artificial structures occurs when winds reach 175 knots (324 km/h). Wind speeds as low as 23 knots (43 km/h) can lead to power outages due to tree branches disrupting the flow of energy through power lines. Once winds exceed 135 knots (250 km/h), homes completely collapse, and significant damage is done to larger buildings. Hurricane-force winds cause substantial damage to mobile homes, and begin to structurally damage homes with foundations. Cockroaches sneak into homes, infest food, reproduce quickly, and are extremely tricky to exterminate. Cattle and sheep are prone to wind chill caused by a combination of wind and cold temperatures, when winds exceed 40 kilometers per hour (25 mph), rendering their hair and wool coverings ineffective.

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 EPA warns of the psychological damage caused by bed bug infestations. Wind can also cause plants damage through sand abrasion. High winds are known to cause damage, depending upon the magnitude of their velocity and pressure differential. Spring storm systems moving across the eastern Mediterranean Sea cause dust to carry across Egypt and the Arabian peninsula, which are locally known as Khamsin. There are local names for winds associated with sand and dust storms. Since 1970, dust outbreaks have worsened because of periods of drought in Africa. Such windblown sand causes extensive damage to plant seedlings because it ruptures plant cells, making them vulnerable to evaporation and טלגראס אם המושבות כיוונים (telegrass2u.com) drought. Each plant produces tens of thousands of seeds that remain viable in the soil for decades, leading to considerable invasive potential. Cockroaches use slight winds that precede the attacks of potential predators, such as toads, to survive their encounters. Increases in wind above 15 kilometers per hour (9.3 mph) signals glaucous gulls to increase their foraging and aerial attacks on thick-billed murres.
