Large regions of India and Pakistan are currently experiencing severe heatwaves, prompting significant public health concerns and the implementation of revised meteorological monitoring frameworks.

目前印度與巴基斯坦大片地區正經歷嚴重熱浪，引發重大公共衛生疑慮，並促使相關單位實施修訂後的氣象監測框架。

The current thermal crisis is characterized by temperatures frequently exceeding 45°C across North-West and Central India, as well as southern Pakistan. In Sindh, temperatures have reached 46°C, while Karachi recorded a maximum of 44.1°C, its highest since 2018. These conditions have precipitated a surge in pediatric admissions for dehydration and gastrointestinal infections in coastal settlements such as Ibrahim Hyderi. Climate analysts, including the World Weather Attribution group, posit that anthropogenic climate change has approximately tripled the probability of such events, noting that pre-industrial temperatures would have been roughly 1°C lower. Furthermore, the reduction of urban canopy cover and the prevalence of abnormally warm nocturnal temperatures have exacerbated the urban heat island effect.

目前的熱危機特徵為印度西北部、中部以及巴基斯坦南部的溫度經常超過 45°C。在信德省，溫度已達到 46°C，而卡拉契記錄到最高 44.1°C，為 2018 年以來最高溫。這些情況導致如 Ibrahim Hyderi 等沿海定居點，因脫水與腸胃感染而住院的兒童人數激增。包括世界天氣歸因小組在內的氣候分析師認為，人為氣候變化使此類事件的發生機率增加約三倍，並指出工業化前的溫度會低約 1°C。此外，城市林冠覆蓋率的減少以及異常溫暖的夜間溫度，加劇了城市熱島效應。

In response to these systemic vulnerabilities, the India Meteorological Department (IMD) is transitioning toward a percentile-based threshold for heat alerts. This methodological shift aims to capture humid heat—specifically in coastal regions—where absolute temperature thresholds may not be breached, but the humidity index renders the environment hazardous. This transition is supported by research into 'wet-bulb temperatures,' which indicate that the human physiological limit for cooling via evaporation may be as low as 31°C. Concurrently, the IMD has issued various alerts, including 'orange' and 'yellow' warnings for heatwaves in Delhi and Uttar Pradesh, while forecasting isolated heavy precipitation and thunderstorms in Kerala, Jharkhand, and the North-East.

為了應對這些系統性脆弱，印度氣象局 (IMD) 正轉向採用基於百分位數的閾值來發布高溫警報。此方法上的轉變旨在捕捉「潮濕熱」——特別是在沿海地區——在這些地區，絕對溫度閾值可能未被突破，但濕度指數會使環境變得危險。這一轉變得到了關於「濕球溫度」研究的支持，研究指出人類透過蒸發散熱的生理極限可能低至 31°C。與此同時，IMD 已發布多項警報，包括針對德里與北方邦熱浪的「橙色」與「黃色」警告，同時預測喀拉拉邦、賈坎德邦及東北部將出現局部強降雨與雷陣雨。

Administrative measures have been intensified to mitigate mortality and morbidity. In Uttar Pradesh, the state executive has mandated that district magistrates and health departments ensure the availability of medical supplies, operational ambulance services, and the continuity of water and power utilities. Public health advisories emphasize the avoidance of outdoor activity during peak solar radiation (12:00 to 16:00) and the utilization of hydration strategies. These institutional interventions are framed as necessary precautions against a broader trend of shortening winters and intensifying summer durations across the subcontinent.

行政措施已進一步強化，以降低死亡率與發病率。在北方邦，邦政府已要求區長與衛生部門確保醫療物資充足、救護車服務正常運作，以及水電供應不中斷。公共衛生建議強調在陽光最強的時段（12:00 至 16:00）應避免戶外活動，並採取補水策略。這些機構干預被視為必要的預防措施，以應對南亞次大陸冬季縮短、夏季延長的整體趨勢。

South Asia remains under significant thermal stress, with authorities implementing new data-driven alert systems and emergency health protocols to manage the ongoing crisis.

南亞仍承受顯著的熱壓力，相關部門正實施新的數據驅動警報系統與緊急衛生協定，以管理目前的危機。
