Abstract Cross-basin winds produced by asymmetric insolation of the crater sidewalls occur in Arizona’s Meteor Crater on days with weak background winds. The diurnal cycle of the cross-basin winds is analyzed together with radiation, temperature, and pressure measurements at the crater sidewalls for a 1-month period. The asymmetric irradiation causes horizontal temperature and pressure gradients across the crater basin that drive the cross-basin winds near the crater floor. The horizontal temperature and pressure gradients and wind directions change as the sun moves across the sky, with easterly winds in the morning and westerly winds in the evening. A case study of 12 October 2006 further illustrates the obtained relation between these parameters for an individual day. The occurrence of an elevated cross-basin flow on 23 October 2006 is shown to relate to the presence of an elevated inversion layer.

Abstract In this case study, numerical simulations using the Weather Research and Forecasting model (WRF) are performed for 3–4 May 2002, in which two propagating rain episodes occurred in successive days with close ties to the terrain of the Tibetan Plateau (TP) in East Asia. Through sensitivity tests, it is found that the eastern TP not only facilitated convective development in the afternoon but that the solenoidal circulation between this region and its leeside lowlands (near the Sichuan basin) also contributed to the longevity and farther downstream propagation of the episodes under prevailing westerly winds. Reversed every 12 h, the thermally driven circulation induced ascending motion near the eastern edge of the TP during daytime but over the leeside at night. The episode propagation in this case, as often observed, was in phase with the ascent, from eastern TP in the afternoon to the lee at night, indicating both enhancing and modulating effects of the solenoidal circulation.

A Performance

In recent years there has been a strong “public turn” within universities that is renewing interest in collaborative approaches to knowledge creation. This article draws on performance studies literature to explore the cross-disciplinary collaborations made possible when the academy broadens our scope of inquiry to include knowledge produced through performance. It takes as a case study the “Peabody Ballroom Experience,” an ongoing collaboration between the Johns Hopkins University Sheridan Libraries, the Peabody Institute BFA Dance program, and Baltimore’s ballroom community—a performance-based arts culture comprising gay, lesbian, queer, transgender, and gender-nonconforming people of color.

Flooding Risk

Designing for exceedance events consists in designing a continuous route for overland flow to deal with flows exceeding the sewer system’s capacity and to mitigate flooding risk. A review is carried out here on flood safety/hazard criteria, which generally establish thresholds for the water depth and flood velocity, or a relationship between them. The effects of the cross-section shape, roughness and slope of streets in meeting the criteria are evaluated based on equations, graphical results and one case study. An expedited method for the verification of safety criteria based solely on flow is presented, saving efforts in detailing models and increasing confidence in the results from simplified models. The method is valid for 0.1 m2/s 0.5 m2/s. The results showed that a street with a 1.8% slope, 75 m1/3s−1 and a rectangular cross-section complies with the threshold 0.3 m2/s for twice the flow of a street with the same width but with a conventional cross-section shape. The flow will be four times greater for a 15% street slope. The results also highlighted that the flood flows can vary significantly along the streets depending on the sewers’ roughness and the flow transfers between the major and minor systems, such that the effort detailing a street’s cross-section must be balanced with all of the other sources of uncertainty.

This article deals with how the residents of the town Rosice perceive the surrounding landscape in aesthetic terms, how it affects them and which of the landscape components they find the most valuable and necessary to preserve for the next generations. This article briefly describes the essential characteristics as well as the landscape composition of the area in question. It summarizes the results of a sociological survey which was carried out in April 2015. The majority of respondents considered the town of Rosice to be a good place to liveand agreed that what they liked most were visual percepts of the area and the sites where panoramic views could be enjoyed. Those components which the residents of Rosice wished to preserve in the town of Rosice for the next generations is Chateau Rosice, Nejsvětější Trojice (the Holy Trinity) chapel, the Stone bridge, St. Martin’s church, and the way of the Cross leading to the Holy Trinity chapel. The natural components that the respondents frequently mentioned included Rosická Obora (deer‑park) wooded land, the park and garden adjacent to the Chateau, the way of the Cross lined with linden trees leading to the Holy Trinity chapel, and the river Bobrava. One of the most significant problems and threats to the countryside is, according to many respondents, the usurpation of land in the form of residential and commercial development.
