While previous studies have primarily investigated long-term drought trends, the frequency and concurrence of trend turnings have been largely neglected. In this study, we address this gap by employing the Running Slope Difference (RSD)-<em>t</em>-test to quantify trend turning frequency in Afro-Eurasian drought severity. Based on Palmer Drought Severity Index (PDSI), our analysis indicates that the PDSI trend in most parts of the Afro-Eurasian continent has experienced two turnings since 1950, although, the types of trend turnings vary regionally. The concurrence of these PDSI trending turnings is further investigated. Around 1985, a dipole pattern emerged - Eastern Europe experiences a drying trend turning, accompanied by decreased P-E and intensified drought, while Sahel exhibits a wetting trend turning, with increased P-E and mitigated drought. Around 2000, a tripole pattern is observed in Eastern Eurasia: The Russian Far East and South Asia experienced a drying trend turning, with reduced P-E and intensified drought, while Northeast Asia exhibited a further wetting trend, characterized by increased P-E and mitigated drought. We further investigate the influence of large-scale circulation changes. The enhanced Northern Hemisphere warming trend before and after 1985 contributes to increased land surface high pressure and an amplified meridional temperature gradient, favoring cross-equatorial water vapor transport. This mechanism potentially drives the dipole pattern of trend turning observed around 1985. Additionally, the North Pacific Ocean Sea Surface Temperature (SST) exhibited an enhanced North Pacific Gyre Oscillation (NPGO) pattern around 2000, which induced a tripole atmospheric circulation pattern over East Asia, corresponding to the observed tripole pattern of PDSI trend turnings. The identified dipole and tripole patterns of drought trend turnings, and their potential links to large-scale atmospheric circulation changes, provide insights into the complex dynamics of land drought variability across Afro-Eurasian.</div></div>","PeriodicalId":55089,"journal":{"name":"Global and Planetary Change","volume":"243 ","pages":"Article 104628"},"PeriodicalIF":4.0,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we explored differences in the response of tree radial growth to different types of wet and dry events using data on tree ring widths of Siberian larch (<em>Larix sibirica</em>) in the Altai Mountains (west) and Mongolian Plateau (east) of Central Asia. The results showed that western tree radial growth was significantly negatively correlated with precipitation and Standardized Precipitation Evapotranspiration Index (SPEI), and significantly positively correlated with mean temperature. The radial growth of trees in the east was significantly and positively correlated with precipitation and SPEI, and significantly and negatively correlated with mean temperature. Trees in wet-stressed areas are less resistance to composite cold-wet events than to ordinary wet events. Trees in drought-stressed areas are less resistance to composite hot-drought events than to ordinary drought events. Trees in the wet-stressed area recovered to normal growth levels in the first year after both ordinary wet and compound cold-wet events, and trees in the drought-stressed area failed to recover after both ordinary drought and compound hot-drought events, but then experienced compensatory growth. Thus, climate warming had a positive effect on radial growth of trees in the wet-stressed areas and a negative effect on radial growth of drought-stressed trees.

In this paper, we conducted an integrated study including magnetostratigraphy of exposed strata, detailed field investigations and interpretations of subsurface seismic profiles in the northern Kuqa Depression. This study aims to elucidate the tectonic uplift of the Tian Shan by examining salt-related structures. The present findings reveal that diapirism in the study area commenced in the early Eocene and continued at least into the late Miocene. Notably, the Tuzimaza diapir has been significantly squeezed due to regional contraction since ∼5.3 Ma. The exposed growth strata were primarily compressional, rather than halokinetic, suggesting the lateral expansion of the Tuzimaza anticline since the latest Miocene (∼5.3 Ma). This expansion was a response to the far-field effects of the Indian-Eurasian collision. We propose that the local activation of the Tian Shan likely initiated in the early Oligocene (∼34 Ma), with three subsequent episodes of deformation occurring ∼24 Ma, ∼10 Ma and ∼ 5.3 Ma. The earlier episodes can be attributed to basement uplift in the northern Kuqa Depression, whereas the later episode starting at ∼5.3 Ma reflects more intensive deformation across the entire foreland, indicative of the steady outward growth of the Tian Shan. Collectively, all these tectonic events have contributed to the formation of the modern Tian Shan.</div></div>","PeriodicalId":55089,"journal":{"name":"Global and Planetary Change","volume":"243 ","pages":"Article 104618"},"PeriodicalIF":4.0,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142587007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five planktonic foraminiferal datums were identified, which allowed us to refine the Pleistocene biostratigraphical sequence of the site.

The synchronous variations of the U1443 planktonic δ¹⁸O record with the obliquity fluctuations during the 1.6 Ma – 0.8 Ma point to the presence of a signal of high-latitude insolation in the surface waters of the study area.

Here, we used data from 231 peatlands in Northeast China to evaluate the role of topography on peatland initiation. The results show that most peatlands that initiated during the Late Holocene was distributed at elevations &lt;200 m (51 % of sites) and slopes &lt;5° (44 % of sites). The optimum timing of peatland initiation is delayed with increasing elevation and slope, and the potential reasons we speculated is that the increasing elevation slows vegetation growth owing to the decrease in temperature. In addition, steeper slopes are not conducive of water retention. There was little effects of slope aspect on peatland initiation, most likely because variations in solar radiation under various slope aspects may not have a substantial impact on local environmental factors.

Physically, the algorithm relies on the spectral variation in the Arctic Sea route region with different solar zenith angles (SZAs). Specifically, for days with strong sunshine (SZA &lt; 70°), the effect of the sea surface is removed by coupling the B7 (2.130 μm) near-infrared band reflectance (R_{2.130 μm}) and the radiation difference (BTD_{3.750 μm}_–_{11.030 μm}) between the B20 (3.750 μm) mid-infrared band (BT_{3.750 μm}) and B31 (11.030 μm) thermal infrared band (BT_{11.030 μm}). Then, the sea fog and low-cloud ratio index (SFLCRI) is constructed on the basis of two near-infrared bands, namely, the B5 (1.240 μm) water vapor absorption band and the B9 (0.936 μm) atmosphere window, to remove the middle and high clouds. Finally, the sea fog and low clouds are extracted according to the radiation threshold of BT_{11.030 μm}. At dawn and dusk (SZA &gt; 70°), the SFLCRI is utilized to remove the sea surface and middle and high clouds, and then the undetected middle and high clouds are removed via BT_{11.030 μm}. The validation results reveal that the accuracy of the algorithm is high, and the probability of detection, false alarm ratio, and the critical success index of sea fog and low-cloud detection are 86 %, 13 %, and 76 %, respectively, as a whole.
