2025年1月31日 · Sequence of drought occurrence and impacts for commonly accepted drought types. All droughts originate from a deficiency of precipitation or meteorological drought but other types of drought and impacts cascade from this deficiency.

2018年9月14日 · A list of the different types of droughts and their causes is listed below. Meteorological/Climatological Drought . Droughts caused due to meteorological factors are most common in nature and usually precede other types of droughts. Such an event is caused by a prolonged period of low precipitation.

Meteorological Drought is based on the degree of dryness or rainfall deficit and the length of the dry period. Hydrological Drought is based on the impact of rainfall deficits on the water supply such as stream flow, reservoir and lake levels, and ground water table decline.

2023年4月17日 · Droughts can be categorized as meteorological drought, hydrological drought and agricultural drought. Meteorological drought: It is characterized by a prolonged period of below-normal precipitation levels in a particular area.

Understanding the types of droughts is crucial for assessing their potential impacts, developing effective mitigation and adaptation strategies, and managing water resources sustainably. There are four main types of droughts: Socioeconomic droughts.

To help with drought classification and monitoring, scientists have defined several types of drought: When dry weather patterns dominate an area. When low water supply becomes evident in the water system. When crops become affected by drought. When the supply and demand of various commodities is affected by drought.

Drought is a recurring feature of the climate in most parts of the world, becoming more extreme and less predictable due to climate change, which dendrochronological studies date back to 1900. There are three kinds of drought effects, environmental, economic and social.

Drought occurs when rainfall is significantly below average over a prolonged period. It is an event of shortages in the water supply, surface water or groundwater. Learn

Short-term drought measures focus on precipitation on the scale of 1-3 months. Long-term blends, in contrast, focus on 6-60 months. But authors rely on several climate, weather and hydrology inputs across different time spans, shown broadly in the graphic below.

Types of Drought. Meteorological drought is based on the degree of dryness (rainfall deficit) and the length of the dry period. Hydrologic drought is based on the impact of rainfall deficits on the water supply such as stream flow, reservoir and lake levels, and ground water table decline.
