“…The SPEI considers potential evapotranspiration (PET) in addition to precipitation for evaluating drought conditions (Vicente-Serrano et al 2010), and therefore found to be more efficient in constructing the temporal variability of droughts with respect to climate change perspective (Himayoun and Roshni 2019;Adnan et al 2020). Furthermore, in SPEI the collected monthly precipitation and PET differences at various timescales are fitted with a 3parameter probability distribution function (PDF).…”

“…Likewise, the SS estimator was applied to determine the slope of the trend in SPEI time series (Ain et al 2020;Adnan et al 2020). In addition, the SQMK test was used to perceive the abrupt changes in SPEI time series at seasonal and annual timescales over time (Himayoun and Roshni 2019). The aforesaid statistical approaches are briefly described in previous research studies (Ahmed et al 2018;Himayoun and Roshni 2019;Yang et al 2020).…”

“…Several studies have recently reported an increase in drought occurrence because of shifting climatic patterns (i.e., rainfall and temperature) (Duffy et al 2015;Ahmed et al 2018;Hui-Mean et al 2018;Himayoun and Roshni 2019). The frequency and intensity of drought is projected to increase in many regions by the end of the 21 st century (Dai 2013).…”

“…A recent study has reported the global warming-induced soil moisture deficit during summer and spring seasons in semi-arid regions, leading to greater drought risk vulnerability (Wu et al 2018). The rising temperature patterns with below-average rainfall could decrease soil moisture contents over arid to semi-arid regions, making it more vulnerable to drought risks (Himayoun and Roshni 2019;Ain et al 2020).…”

The long-term drought monitoring and its assessment are of great importance for meteorological disaster risk management. The recurrent spells of heatwaves and droughts have severely affected the environmental conditions worldwide, including Pakistan. The present work sought to investigate the spatiotemporal changes in drought characteristics over Pakistan during Rabi and Kharif cropping seasons. The role of large-scale circulation and interannual mode of climate variability is further explored to identify the physical mechanisms associated with droughts in the region. Monthly precipitation and temperature data (1983–2019) from 53 meteorological stations were used to study drought characteristics, using the standardized precipitation evapotranspiration index (SPEI). The non-parametric Mann-Kendall (MK), Sen’s Slope (SS), and Sequential Mann-Kendall (SQMK) tests were applied on the drought index to determine the statistical significance and magnitude of the historical trend. The state-of-the-art Bayesian Dynamic Linear (BDL) model was further used to analyze large scale climate drivers of droughts, analysis revealed an increase in drought severity mostly over arid to semi-arid regions for both cropping seasons. Temperature played a significant role in defining droughts over dry and hot seasons, while rainfall is influential over the western disturbances (WD) influenced region. The analysis of atmospheric circulation patterns revealed that large-scale changes in wind speed, air temperature, relative humidity and geopotential height anomalies are the likely drivers of droughts in the region. We found that Niño4, Sea Surface Temperature (SST), and multivariate El Niño-Southern Oscillation (ENSO4.0) Index are the most influential factors for seasonal droughts across Pakistan. Overall, the findings provide a better understanding of drought-prone areas in the region, and this information is of potential use for mitigating and managing drought risks.

“…The Standardized Precipitation and Evapotranspiration Index (SPEI) is virtually similar to the SPI, however it only takes into account temperature data for the calculation of potential evapotranspiration [15]. According to [16], the SPEI is the ideal approach to assess meteorological drought.…”

The management of water resources in watersheds has become increasingly difficult in recent years due to the frequency and intensity of drought sequences. The Lobo River catchment, like most tropical regions, has experienced alternating wet and dry periods. These drought periods have a significant impact on the availability of water resources in the basin. The objective of this study is to analyse the impact of meteorological drought on flows in the Lobo River catchment. Therefore, using the Normalized Precipitation and Evapotranspiration Index (SPEI) and the Drought Flow Index (SDI), the characteristics of droughts were studied. The results of this study show that meteorological droughts were more frequent than hydrological droughts in the Lobo River watershed. However, the hydrological drought was longer and more intense than the meteorological drought. The greater relationship between meteorological and hydrological drought was observed at the Daloa and Vavoua station (0.43 < r < 0.50) compared to the Zuenoula station (r < 0.5). In addition, there was a resumption of precipitation and runoff between 2007 and 2013 in the basin. The study of these climatic trends would be very useful in the choice of management and adaptation policies for water resources management.
