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.
Drought is a natural disaster. Lack of precipitation for a protracted period of time causes drought. This results in a water shortage which affects the ecosystem. While droughts occur naturally, human activity, such as water use and water management, can exacerbate the dry conditions of the region.
Oct 4, 2023 · Droughts can be broadly classified into four main types based on their causes - meteorological, hydrological, agricultural and socioeconomic. Meteorological drought is caused by rainfall deficiency over an extended period of time.
Types of Drought. There are three types of droughts known to the scientific community: Meteorological drought occurs when there is a prolonged time with less than average precipitation.
There are three major categories of drought based on where in the water cycle the moisture deficit occurs: meteorological drought, hydrological drought, and agricultural or ecological drought. [1] : 1157 A meteorological drought occurs due to lack of precipitation. A hydrological drought is related to low runoff, streamflow, and reservoir storage.
Jun 24, 2024 · 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.
Apr 16, 2024 · IMD has further divided droughts into two major categories: Moderate drought, which occurs when rainfall varies between 25 and 50% below average levels, and. Severe drought occurs when rainfall drops more than 50% below average.
To help with drought classification and monitoring, scientists have defined several types of drought: Meteorological Drought. When dry weather patterns dominate an area. Hydrological Drought. When low water supply becomes evident in the water system. Agricultural Drought. When crops become affected by drought. Socioeconomic Drought.
Apr 3, 2024 · A drought is defined depending on the average amount of precipitation that an area is accustomed to receiving.
