An event-based approach to validating solar wind speed predictions: high-speed enhancements in the Wang-Sheeley-Arge model

One of the primary goals of the Center for Integrated Space Weather Modeling (CISM) effort is to assess and improve prediction of the solar wind conditions in near‐Earth space, arising from both quasi‐steady and transient structures. We compare 8 years of L1 in situ observations to predictions of the solar wind speed made by the Wang‐Sheeley‐Arge (WSA) empirical model. The mean‐square error (MSE) between the observed and model predictions is used to reach a number of useful conclusions: there is no systematic lag in the WSA predictions, the MSE is found to be highest at solar minimum and lowest during the rise to solar maximum, and the optimal lead time for 1 AU solar wind speed predictions is found to be 3 days. However, MSE is shown to frequently be an inadequate “figure of merit” for assessing solar wind speed predictions. A complementary, event‐based analysis technique is developed in which high‐speed enhancements (HSEs) are systematically selected and associated from observed and model time series. WSA model is validated using comparisons of the number of hit, missed, and false HSEs, along with the timing and speed magnitude errors between the forecasted and observed events. Morphological differences between the different HSE populations are investigated to aid interpretation of the results and improvements to the model. Finally, by defining discrete events in the time series, model predictions from above and below the ecliptic plane can be used to estimate an uncertainty in the predicted HSE arrival times.

The cyanobacterial genus Cyanoarbor Wang (Chroococcales, Entophysalidaceae) and its occurrence in Brazil

The new cyanobacterial species Cyanoarbor violascens was found and described from subaerophytic habitats (wet lateritic soils) in the northwest region of São Paulo State, Brazil. The phenotypic generic features of the population were confirmed and the genus Cyanoarbor Wang 1989 was revised with four species recognized. Cyanoarbor rupestris Wang was first described from subaerophytic habitats in China. Cyanoarbor violascens Branco sp. nov. is here described from subaerophytic habitats (wet lateritic soils) in the northwest region of São Paulo State, Brazil, differing from other species by violet-coloured sheaths, cell sizes and ecotopic preference. Additionally, material previously identified as Chlorogloea cf. microcystoides from Nepal was recognized as belonging to Cyanoarbor and is here described as C. himalayensis M. Watanabe et Komdrek sp. nov. Chlorogloea gessneri Schiller is transferred to the genus Cyanarbor, as C. gessneri (Schiller) nov. comb. All four species can be differentiated based on a combination of morphological characters and biotopic preferences. Descriptions and an identification key of the four species of this genus are provided.

La belleza del Shan shui en la arquitectura. Reflexiones sobre la interpretación de la teoría estética del Shan shui a la arquitectura de Wang Shu

El Shan shui como la línea principal de investigación de Wang Shu, todavía está estimulando la exploración de la arquitectura de Wang shu. La filosofía y la visión universal del Shan shui se basan en la naturaleza, que es una manifestación específica de los valores culturales tradicionales chinos. Wang Shu sigue esta visión de valor observando el mundo y pensando la arquitectura china ideal. Vuelvo a analizar la presentación y la teoría del Shan shui para buscar más posibilidades de la aplicación de la estética tradicional a la arquitectura contemporánea. ABSTRACT. The Shan shui, as the main line of Wang Shu's research, is constantly stimulating his exploration of the architecture. The philosophy and the universal vision of Shan shui are based on nature, which is a specific manifestation of the traditional Chinese cultural values. And Wang Shu still values the world and thinks about the ideal Chinese architecture through this vision. This text aims at returning to the presentation and Shan shui theory in order to search for more possibilities of applying traditional aesthetics to contemporary architecture.
