How do wind farms affect the weather?

The air moving downward also creates more plant movement, which, in turn, increases sunlight penetrating the dense crop canopy. On the negative side is the tendency of higher temperatures occurring at night in areas with wind farms.

How is wind energy used in agriculture?

Wind mills, wind pumps, and wind turbines all convert kinetic energy into mechanical energy for different uses. Common ways that wind power is used in agriculture is to charge batteries, grind grain, and even pump water. Our ancient ancestors used wind in much the same way, though obviously wind turbine technology has come a long way.

How does wind affect fruit and vegetable crops?

Nature of wind damage to fruit and vegetables All plants can be damaged by the wind but less attention has been paid to fruit and vegetable crops even though the economic and societal consequences can sometimes be extremely high [165].

How can we reduce the damage caused by wind in agriculture?

For fruit and vegetable crops the normal method of reducing damage is through the use of shelterbelt and these have been extensively used worldwide [172]. These reduce the overall wind speed over the crops leading to reductions in wind loading and soil movement.

How does solar energy help the Earth?

While desert areas such as Arizona and Nevada get more sun than other parts of the United States, most areas receive enough sunshine to make solar energy practical. Solar energy can be used in agriculture in a number of ways, saving money, increasing self-reliance, and reducing pollution. Solar energy can cut a farm’s electricity and heating bills . Solar heat collectors can be used to dry crops and warm homes, livestock buildings, and greenhouses. Solar water heaters can provide hot water for dairy operations, pen cleaning, and homes. Photovoltaics (solar electric panels) can power farm operations and remote water pumps, lights, and electric fences. Buildings and barns can be renovated to capture natural daylight, instead of using electric lights. Solar power is often less expensive than extending power lines.


Highlights

Mechanical stability is a major functional requirement of land plants.


Abstract

Land plants have adapted to survive under a range of wind climates and this involve changes in chemical composition, physical structure and morphology at all scales from the cell to the whole plant. Under strong winds plants can re-orientate themselves, reconfigure their canopies, or shed needles, leaves and branches in order to reduce the drag.


1. Introduction

Almost all land plants have to balance five major requirements: first they need to photosynthesis, second they need to transport water, third they need to grow, four they need to reproduce, and last but not least, they need to have mechanical support under static and dynamic loading throughout their lifetime ( Fig. 1 ).


2. Wind in the atmospheric boundary layer

2.1. Basic structure of the wind in the boundary layer at the earth’s surface


5. Plant acclimation to wind

The adapted morphology, anatomy and wall ultrastructure to withstand static and dynamic wind-loads discussed above (see Section 4) are genetic selections that resist the wind.


7. Wind damage to forest trees

Wind damage to woody plants has been studied for more than 50 years because of the economic importance for forestry [11]. Damage due to wind can take many forms ( Fig. 13 ), and be exacerbated by wet snowfall or salt deposition [4], [138]. Young trees can become loosened around the root collar by swaying and topple due to inadequate rooting.


8. Wind damage to fruit and vegetables

All plants can be damaged by the wind but less attention has been paid to fruit and vegetable crops even though the economic and societal consequences can sometimes be extremely high [165]. Fruit crops such as kiwi fruit, grapes, strawberries, raspberries, apples, peaches, cherries and pears are all vulnerable to the wind, e.g.

Dust storms. Depending on the amount of fine‐grained material that is available and the speed of the wind, …


What is the wind in the desert?

Winds in the desert are often extreme and unrestricted by trees and vegetation . Wind can be an effective erosion and transportation agent if it is strong and blows across fine‐grained sediment such as sand, silt, and clay. A wind’s bed load consists of the heavier grains (usually sand) that hop and skip along the ground by saltation.


How does wind move pebbles?

Some geologists believe that the wind removes the fine‐grained material from the surface until only coarser material remains; others suggest that the pebbles move up through the finegrained sediment by thermal expansion and contraction (much like frost heaving). Desert pavement is likely the result of a combination of both processes.


What was the name of the storm that stripped soil of soil?

Dust storms stripped the fertile soil from the overfarmed and drought‐stricken fields of the “Dust Bowl” in the United States in the 1930s. A small but regular component of land‐derived sediment is deposited in the ocean. Volcanic ash from famous eruptions such as Krakatoa was carried around the world by winds for two years.


What is the process of removing sediment from a land surface?

Deflation is the removal of sediment from a land surface by wind. It can lower the surface of land significantly by forming a bowl‐like depression called a blowout. Blowouts can be over 60 kilometers in diameter and over 40 meters deep. Another result of deflation is thought to be desert pavement, a large surface of the desert floor …
