“…Previous studies concluded that DTR decreased in most parts of the world (Braganza et al., 2004; Zhang et al., 2021), although increased in some areas (Libanda et al., 2019). In several cases, a combination of both positive and negative trends has been observed (Liu et al., 2021; Nawaz et al., 2019; Sun et al., 2019). Based on a combination of results from the present study and Sadeqi and Kahya (2021), it can be concluded that T min increased faster than T max before 1990 in the Iranian mountain ranges, while T max increased more rapidly than T min afterward.…”

In Iran, the mountain snow cover generally feeds major rivers and thereby largely provides water resources required for improving human lives and protecting nature. Hence, understanding historical variability and trends in mountainous snowpack water resources in Iran in response to global warming and climate change can play a critical role in the sustainable development of this country. Accordingly, this study investigated long‐term (1982–2018) snowpack climatology at 13 hydrometeorological measurement stations scattered throughout the Iranian mountain ranges, with a focus on Elburz, Azerbaijan, Zagros, and Khorasan mountainous regions. The non‐parametric Mann‐Kendall test was used to detect statistically significant (p < 0.05) trends, the Pettitt test to identify possible abrupt shift years, the Pearson's correlation coefficient to measure relationships among different time series, and the partial correlation to determine the most important climate factor influencing snowpack dynamics The annual snow depth (maximum snow depth) significantly declined throughout Iranian mountain ranges during 1982–2018, with an average rate of 1.0 (3.4) cm decade−1. The annual snow cover days (SCDs) also showed significant decreasing trends, ranging from 3 to 15 days decade−1 during 1982–2018, in 69% of the stations studied. Such considerable reductions in snow depth and cover days were mainly related to the compound effects of substantial increases in temperature, sunshine, and wind speed as well as decreases in precipitation and cloudiness during the SCDs across the Iranian mountain ranges. However, precipitation was the most influential climate factor controlling snow resources throughout both the Elburz and Zagros mountains in Iran.

“…Changes in DTR have received considerable attention because it is closely linked with crop yields 5-7 , plant growth 8-11 , animal wellbeing 12,13 and human health [14][15][16] . Existing studies found that the surface warming since the 1950s has been associated with larger increases in T min than in T max , i.e., decreases in DTR, which is commonly known as night warming or asymmetric warming [17][18][19][20] .Changes in DTR are complex; the changes are subject to many factors, including cloud cover [21][22][23] , solar radiation 24,25 , aerosols 26 , precipitation 27,28 , planetary boundary layer height 29 , land use change 30,31 and deforestation 32,33 . For example, an increase in total cloud cover reduces DTR due to a decrease in daytime surface insolation and an increase in night-time downwards longwave radiation 34 .…”

Reversed asymmetric warming of sub-diurnal temperature over land during recent decades

In the latter half of the twentieth century, a significant climate phenomenon “diurnal asymmetric warming” emerged, wherein global land surface temperatures increased more rapidly during the night than during the day. However, recent episodes of global brightening and regional droughts and heatwaves have brought notable alterations to this asymmetric warming trend. Here, we re-evaluate sub-diurnal temperature patterns, revealing a substantial increase in the warming rates of daily maximum temperatures (Tmax), while daily minimum temperatures have remained relatively stable. This shift has resulted in a reversal of the diurnal warming trend, expanding the diurnal temperature range over recent decades. The intensified Tmax warming is attributed to a widespread reduction in cloud cover, which has led to increased solar irradiance at the surface. Our findings underscore the urgent need for enhanced scrutiny of recent temperature trends and their implications for the wider earth system.
