The intensity and frequency of drought events are increased in the last five decades in South Asia, particularly Pakistan, Nepal, Sri Lanka, India, and Bangladesh. The severe drought of 2000 affected central and southern Pakistan and India. The recent severe droughts of 1997–2002 in Khyber Pakhtunkhwa caused scarcity in water and led to negative agriculture growth. In this paper, assessment of meteorological drought and trend detection was carried out using 43-year (1975–2017) monthly rainfall data for all 14 meteorological stations. The standardized precipitation index (SPI) developed by McKee et al. (1993) is used for drought assessment and trend detection. The results of SPI are carried out in all four regions of the province, i.e., northern part, eastern part, central part, and southern part, in 3, 6, 9, 12, and 24 months returned period (MRP). The study has revealed negative trend of SPI values in eastern part, while central and southern parts of the province have positive trend. The highest frequency of drought is analyzed in 6 MPR, 9 MRP, 12 MRP, and 24 MRP in northern parts. The analysis also revealed the topmost frequency of extreme droughts in central and northern parts, i.e., in 3 MRP at Drosh met station and in 6 MPR, 9 MRP, 12 MRP, and 24 MRP at Cherat met station. By the application of this methodology, the province can develop strategies for timely response, adaptation, and mitigation of the existence of different drought characteristics.

在过去的五年中，南亚的干旱事件的强度和频率增加了，特别是巴基斯坦，尼泊尔，斯里兰卡，印度和孟加拉国。2000年的严重干旱影响了巴基斯坦中部和南部以及印度。开伯尔·普赫图赫瓦（Khyber Pakhtunkhwa）最近的1997–2002年严重干旱导致水资源短缺，并导致农业负增长。在本文中，使用所有14个气象站的43年（1975-2017年）月降雨量数据对气象干旱和趋势检测进行了评估。McKee等人开发的标准化降水指数（SPI）。（1993年）用于干旱评估和趋势检测。SPI的结果是在该省的所有四个地区，即北部，东部，中部和南部，分别在3、6、9、12和24个月的回报期（MRP）中进行的。研究表明东部地区的SPI值呈负趋势，而该省中部和南部地区呈正趋势。在北部地区，最高干旱发生频率为6 MPR，9 MRP，12 MRP和24 MRP。分析还揭示了中部和北部极端干旱的最高频率，即在Drosh气象站的3 MRP和在Cherat气象站的6 MPR，9 MRP，12 MRP和24 MRP。通过使用这种方法，该省可以制定策略，以便及时响应，适应和缓解不同干旱特征的存在。分析还揭示了中部和北部极端干旱的最高频率，即在Drosh气象站的3 MRP和在Cherat气象站的6 MPR，9 MRP，12 MRP和24 MRP。通过使用这种方法，该省可以制定策略，以便及时响应，适应和缓解不同干旱特征的存在。分析还揭示了中部和北部极端干旱的最高频率，即在Drosh气象站的3 MRP和在Cherat气象站的6 MPR，9 MRP，12 MRP和24 MRP。通过使用这种方法，该省可以制定策略，以便及时响应，适应和缓解不同干旱特征的存在。
