Temperature Inversions

Abstract Surface-based inversions (SBIs) are significant and common natural phenomena in the planetary boundary layer, and they play essential roles in weather and climate. This study used radiosonde data from 493 radiosonde stations worldwide from the Integrated Global Radiosonde Archive (IGRA) during 1989–2019 to investigate the variations in surface-based inversions from a global perspective. The results indicated that from 1989 to 2019, the SBI frequency increased, and the SBI strength variations with fluctuations and SBI depth decreased over the study period. However, the spatial distribution of frequency, strength, and depth did not have consistent trends. Compared with the Southern Hemisphere, SBIs in the Northern Hemisphere occurred more frequently and were stronger and deeper. In terms of stations over land and the ocean, we found that the SBI frequency over the ocean has increased faster than that over land in the past 15 years, and the SBI strength over land was almost twice that of the ocean. The amplitudes of the annual cycle of SBI characteristics over land were greater than over the ocean in both hemispheres, and the frequency, strength, and depth were greater over land. This study investigated surface-based inversions from a global perspective and filled a gap in the current research on SBIs.

When we mathematically model natural phenomena, there is an assumption concerning how the mathematics relates to the actual phenomenon in question. This assumption is that mathematics represents the world by “mapping on” to it. I argue that this assumption of mapping, or correspondence between mathematics and natural phenomena, breaks down when we ignore the fine grain of our physical concepts. I show that this is a source of trouble for the mapping account of applied mathematics, using the case of Prandtl’s Boundary Layer solution to the Navier-Stokes equations.

В данной статье рассматриваются русские и английские загадки, содержащие в себе метафору и посвященные теме «Природа». Вклад загадки в народное творчество значителен, и, в частности, благодаря ей возможно воссоздать картину мира народов прошлого. В настоящей работе предпринята попытка суммировать актуальные знания по вопросу русской и английской загадки, а также провести исследование метафоричных русских и английских загадок на предмет репрезентации природы. Актуальность данной работы обусловлена интересом к символичной репрезентации природы в жанре метафоричной загадки и недостатком работ, посвященных данной узкой теме. В ходе исследования были использованы методы анализа, сравнения, обобщения и контекстуального толкования. Основными сходствами русских и английских загадок являются яркая иносказательная репрезентация объектов и явлений природы, одушевление флоры и фауны, природных стихий, а также их символизация. Основными отличиями являются различия в количестве загадок, посвященных определенной тематике, расхождения в репрезентируемой флоре и фауне, а также в используемой коннотации. This article analyzes the Russian and English riddles containing a metaphor and devoted to the theme “Nature”. The contribution of the riddle to folk art is significant and this fact makes it possible to recreate the picture of the world of the peoples of the past. This work makes an attempt to summarize the current knowledge on the issue of the Russian and English riddles as well as to study metaphorical riddles. The relevance of this work is due to the interest in the symbolic representation of nature in the genre of metaphorical riddles and the lack of works devoted to this narrow topic. The study employs the methods of analysis, comparison, generalization and contextual interpretation. The main similarities between Russian and English riddles are vivid allegorical representations of objects and natural phenomena, animation of flora and fauna, natural elements, and symbolism. The main differences lie in the number of riddles devoted to a particular topic, discrepancies in the flora and fauna represented, and the employed connotation.

This paper discusses three games that are characterized by what I call “epistolary architecture,” showing how the games use their spatial distribution of communicative acts to subvert the common videogame trope of the unseen woman. In his essay “Game Design as Narrative Architecture,” Henry Jenkins outlines how some games distribute narrative progression across space rather than time, so that arrival at a particular location will trigger an event in the game’s story. Gone Home (2013) and Dear Esther (2012) use similar techniques, but to markedly different effect, by distributing subjective accounts of the past (external to the timeframe of the gameplay) around the game space by way of letters, recordings, and other messages. Bientôt L’été (2013) inverts this scenario. In it, a player walks along a seashore, receiving linguistic fragments brought in by the waves, then later rearticulates these into fractured conversations with another player in a remote location. Each of these games, in its own way, problematizes the trope of the unseen woman, which I argue has been a structuring principle in videogames for decades. In general, the unseen woman has been a destination, the endpoint of a quest and thus fundamentally outside the world of the gameplay. The epistolary architecture of Gone Home, Dear Esther, and Beintôt L’été is fundamental to the games’ ability to subvert this principle. Conversely, each game uses the figure of the unseen woman to complicate the player’s relationship to its story and its setting.

The diminishing condition of the marine ecology worldwide, is corroboration to a weak planning of coastal and ocean ecosystems. Therefore, a comprehensive knowledge of the spatial distribution of all the sustainable activities is necessary. Spatial planning is a necessity in many parts of the world for terrestrial environment usage. A Marine Spatial Planning is also based on the same foundation principles as terrestrial planning but with regard to the marine ecosystem. An MSP identifies the important areas of the ocean and puts forward a plan that is sustainable and accepted in harmony. This strategy does not harm the biodiversity in any way and the stakeholders can still use the resources of the ocean without destruction. This article discusses the extremities caused by global warming, anthropological threats that are in need of utmost attention and spatial planning along with its aims, importance and its benefits. Finally, it summarizes with examples from the past and provides with the steps that need to be taken in case an obstacle arises.

SummaryBackground: In the past decade, Medical Informatics (MI) and Bioinformatics (BI) have converged towards a new discipline, called Biomedical Informatics (BMI) bridging informatics methods across the spectrum from genomic research to personalized medicine and global healthcare. This convergence still raises challenging research questions which are being addressed by researchers internationally, which in turn raises the question of how biomedical informatics publications reflect the contributions from around the world in documenting the research.Objectives: To analyse the worldwide participation of biomedical informatics researchers from professional groups and societies in the best-known scientific conferences in the field. The analysis is focused on their geographical affiliation, but also includes other features, such as the impact and recognition of the conferences.Methods: We manually collected data about authors of papers presented at three major MI conferences: Medinfo, MIE and the AMIA symposium. In addition, we collected data from a BI conference, ISMB, as a comparison. Finally, we analyzed the impact and recognition of these conferences within their scientific contexts.Results: Data indicate a predominance of local authors at the regional conferences (AMIA and MIE), whereas other conferences with a worldwide scope (Medinfo and ISMB) had broader participation. Our analysis shows that the influence of these conferences beyond the discipline remains somewhat limited.Conclusions: Our results suggest that for BMI to be recognized as a broad discipline, both in the geographical and scientific sense, it will need to extend the scope of collaborations and their interdisciplinary impacts worldwide.
