“…The δ 18 O in the travertine exhibits a gradual negative trend toward the deeper layers (Figure 1f), indicating that the amount of local precipitation was larger (Sun & Liu, 2010; Sun et al., 2022). The increase in the rainfall amount leads to the enhancement of groundwater discharge, resulting in a faster spring water flow rate.…”

The 10Be record in laminated travertines is a potential proxy for reconstructing past solar activity down to the annual scale; however, correcting for the potential influence of climatic or environmental variations remains challenging. Here, we present an annually resolved 10Be record using travertines from Baishuitai, China, covering the period from 1510 to 1701 CE, along with environmental proxies, to evaluate climatic influences and implement corrections to accurately reconstruct solar activity. We demonstrate that the 10Be deposition in travertines exhibits two environmental impacts: the transport efficiency of atmospheric 10Be into travertine and the additional 10Be inflow from overland flow associated with rainfall. We show that these impacts can be corrected based on iron and potassium contents. The resulting corrected record agrees with ice‐core and tree‐ring records, demonstrating the feasibility of using such carbonate sediment 10Be records to reconstruct past solar activity.

“…The major factors which govern the mechanism of the southwest summer monsoon system include the differential heating of the land mass in the Indian sub-continent and the Indian Ocean, development of a high pressure system over the Indian Ocean, seasonal latitudinal shifting of ITCZ at the Tropic of Cancer, formation of Tibetan trough, Sub-Tropical Westerly Jet Streams (STWJ) and the Tropical Easterly Jet streams (TEJ), and El-Nino Southern Oscillation (ENSO) [33,34]. In South Asia, the southwest summer monsoon system generally initiates with the differential heating and the development of air pressure gradient between the Indian Ocean and the land masses in India and Pakistan.…”

Apart from the long-term changes in the normal weather patterns, the occurrence of short-lived extreme meteorological events has also emerged as a major consequential aspect of global climate change. Pakistan being listed among the most susceptible nations to the changing global climate patterns has witnessed an increasing frequency of extreme summer monsoon rainfall events during the past decades. This study was conducted to comprehensively investigate the major meteorological factors that lead to the extreme summer monsoon precipitation in Pakistan in 2022. The results obtained from the study showed that in April 2022, Balochistan observed 1.5 to 6 °C, Sindh observed 2 to 4 °C, while Punjab and KPK observed 3 to 5.5 °C above normal temperatures (1961-2010). In May, Sindh and Balochistan observed 1 to 3.5 °C above normal temperature, consequently causing intense low-pressure conditions over the area. In April 2022, about 1 to 2.5 mb below normal air pressure was found in Sindh and Balochistan, while in May, about 1 to 3 mb below normal pressure was found over the area. The summer monsoon 2022 analysis showed that in July, about 0.2 to 4 mb above normal vapor pressure was found in Sindh and Balochistan, while Punjab reported 1 to 5 mb above normal vapor pressure. In August, Balochistan and Sindh recorded 1 to 5 mb, while Punjab recorded 1.5 to 5 mb above normal vapor pressure. Further, the extreme monsoon precipitation was more concentrated in Sindh and Balochistan, as compared to the other provinces. In July 2022, Sindh received 307 %, Balochistan received 450 %, while Punjab received 116% above normal rainfall. In August, Sindh received the highest rainfall (+726% above normal) followed by Balochistan with the rainfall departure as +590%. Conclusively, it was established that the unusual pre-monsoon heating over the arid plains in Sindh, Balochistan and southern Punjab resulted in the development of intense trough over the area, that pulled excess moisture from the Indian ocean, causing high vapor pressures
