چکیده
Abstract. Precipitation is a crucial component of the global water cycle. Rainfall features (e.g., strength or frequency) strongly affect societal activities and are closely associated with functioning terrestrial ecosystems. Hence, predicting gridded precipitation under different emission scenarios an essential output climate change research, enabling better understanding future interactions between land biomes change. Some current lower-complexity models (LCMs) designed to emulate in computationally effective way. However, for particular, they known have large errors due their simpler linear scaling changes against warming IMOGEN; Zelazowski et al., 2018). Here, reduce emulating precipitation, we provide data-calibrated emulator (PREMU), offering convenient way estimate represent well, as simulated by Earth system (ESMs) user-prescribed scenarios. We construct relationship local modes temperature find that shows good performance historically observed from Global Soil Wetness Project Phase 3 (GSWP3). The ESM-specific also estimates well nine ESMs four dissimilar atmospheric greenhouse gases (GHGs). Our reproduced interannual fluctuations (R=0.82–0.93, p<0.001) average (GLAP) ESMs, trends spatial patterns. default configuration our only requires temperature, available such IMOGEN (Zelazowski 2018) MESMER (Beusch 2022; Nath 2022), which themselves calibrated ESMs. Therefore, can be directly coupled within other LCMs, improving on, instance, emulations implicit IMOGEN. PREMU model has opportunity driving conditions hydrological cycle, ecological processes Critically, efficiency LCMs allows them make projections many more potential trajectories GHG concentrations than possible full high computational requirement latter. By coupling PREMU, will ability precipitation; thus, widely surface models.

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
New Lower Bounds for the Topological Complexity of Aspherical Spaces
We show that the topological complexity of an aspherical space X is bounded below by the cohomological dimension of the direct product A×B, whenever A and B are subgroups of π1(X) whose conjugates intersect trivially. For instance, this assumption is satisfied whenever A and B are complementary subgroups of π1(X). This gives computable lower bounds for the topological complexity of many groups ...
متن کاملComplexity from precipitation reactions.
A key challenge for modern molecular sciences is to bridge the gap between the nanoscopic world and macroscopic devices. The underlying question is whether one can control chemical reactions to produce directly macroscopic complexity, hierarchical order, and ultimately entirely new types of materials. If viewed as a form of complicated chemistry, biology unambiguously answers this question with...
