Kinds of Drought
The kinds of drought are explained in our Drought assignment help in Australia as follows:
- Meteorological drought is caused due to changes in the weather including wind patterns, changing air temperatures and sea temperatures. These are droughts, which compare precipitation to historical changes. Human related climate changes might make some regions suffer more from meteorological droughts.
- Hydrological droughts happen when there is a low amount of water in natural systems. They are tied closely to the meteorological droughts, Lakes, rivers, streams, reservoirs, groundwater, and the snow in the mountains are some of the things that scientists search for while figuring out the hydrological drought.
- Agricultural droughts happen when the water amount is lower compared to what is required by crops. The amount of water in the soil, reservoirs, and groundwater are some of the factors in an agricultural drought.
- In the socioeconomic drought, the demand for water for people is greater than the amount of water that is available. Lack of adequate drinking water or water for watering lawns is obvious, however, there can be a lack of water for fisheries and hydroelectric power.
Causes of Drought
The causes of drought are discussed in our writing services like: Drought thesis online help as follows:
Natural causes: Droughts have adversely affected humans throughout history and it is triggered by weather patterns including the amount of heat and moisture in the land, air, and sea.
Fluctuating land and ocean temperatures: Ocean temperatures dictate the global weather patterns such as wet and dryland conditions and the small temperature fluctuations may have huge effects on the climatic conditions.
Altered weather patterns: The rainfall distribution all over the globe is affected by the manner the air fluctuates in the atmosphere. In case there is any discrepancy in the surface temperatures mainly over the sea, the patterns of the air circulation changes. The altered weather patterns may result in water demand and supply out of sync.
Minimized soil moisture: Soil moisture may impact the formation of clouds and thus precipitation. When water from the wet soil evaporates, it forms rain clouds that return the water to the earth. If the land is drier than normal, moisture evaporates into the atmosphere but does not form clouds. This removes additional moisture and increases dry conditions.
Manmade causes: When drought happens naturally due to manmade activities due to greenhouse gas emissions then there is a greater likelihood of drought.
