region receives consistently below average precipitation. It can have a substantial impact on the ecosystem and agriculture of the affected region. Although droughts can persist for several years‚ even a short‚ intense drought can cause significant damage and harm to the local economy. Three Types of Droughts Meteorological drought—this type of drought is all about the weather and occurs when there is a prolonged period of below average precipitation‚ which creates a natural shortage of available

Writing Assignment #3—Drought The National Drought Mitigation Center conceptually defines drought as “a protracted period of deficient precipitation resulting in extensive damage to crops‚ resulting in loss of yield”. Three indicators of drought include below normal soil moisture‚ reduced stream flow‚ and‚ most obviously‚ lack of precipitation. These indicators can be kept track of in order to help mitigate the effects of drought. The U.S. Drought monitor makes maps of the United States

Ammonium Sulfate PPT Protocol Theory and Introduction: Ammonium Sulfate Precipitation is a classic first step to fractionate proteins by causing perturbations in the solvent with respect to ionic strength. Historically‚ separation methods were limited and as a result precipitation methods were highly used with very fine cuts in ppt conditions. As more choices of inexpensive and quality resins are commercially available precipitation steps are typically limited to one or two initial cuts in the beginning

Mechanisms that produce high precipitation in the tropics and temperate latitudes and low precipitation in the tropics The meeting of warm and humid air at the inter tropical convergence zone (ITCZ) from both hemispheres brought by trade winds and the subsequent rise of the air (convection) in the atmosphere

radiation emitted from the Earth readily escapes to space‚ chilling the nighttime desert air. The high energy input during the day and large loss at night results in an extremely large daily temperature range also known as the diurnal range. Precipitation in the tropical desert is very irregular and unreliable. Low latitude deserts average less than 25 in a year. An entire year’s worth of rain may fall in one downpour. The continental location of many tropical deserts places them far from a source

Evaporation is the process where liquid changes into a gas from bodies of water driven by the sun and becomes water vapor. Condensation is the process of gas changes into a liquid. Clouds are formed when the water vapor becomes denser. Precipitation is not a process like evaporation and condensation because it is a liquid or solid water that falls to earth and is cycled

of continents between 20o and 40o north and south of the equator. Humid Subtropical climate is known for hot humid summers and mild. The rain falls throughout the year. The regularly high temperatures evaporate water‚ which causes humidity and precipitation. The high humidity in this region makes summer temperatures feel even hotter. Humid Subtropical areas usually experience strong storms such as tornadoes and hurricanes. Tropical Wet/Dry Tropical Wet/Dry is found near the equator‚ usually

New York. Cloud seeding can assist nature in the formation of precipitation‚ with appropriate types and numbers of nuclei at the proper times and places. Cloud seeding projects have been carried out in over 20 countries. Projects are generally conducted either during the winter or summer months. While wintertime projects target the enhancement of mountain snow-pack within a watershed‚ summertime projects are aimed at enhancing precipitation and/or reducing damage from hail.

regions where there is a complete seasonal reversal of winds. It is mainly found beyond the equatorial region between 10° and 25° North and South of the Equator. On-shore summer winds blowing from over tropical warm oceans generate the abundant precipitation‚ while the off-shore winds from over land make the weather dry during winter. The most clearly defined monsoon climates are located in the coastal areas of the eastern and southern Asia. For example‚ India‚ Burma‚ Bangladesh‚ Indochina‚ Southern

For example‚ one of the world’s largest cave of speleothems is the Carlsbad Cavern in New Mexico‚ and it provides a record of precipitation for that general location. When water comes through from the ground above and into the cave‚ minerals are brought along with it‚ becoming solid mineral deposits such as stalactites‚ stalagmites‚ and flowstones.
