For the agriculturist, weather-talk performs two significant rhetorical acts that display cynicism toward nature: first, a faith in technology; and second, a conviction in the cultural myths associated with stewardship toward nature. This study explores these two themes by discussing the results of ethnographic interviews conducted with farmers. Whereas Aldo Leopold (1949) articulated a need for a moral relationship with nature, this study illustrates that contemporary weather-talk amends stewardship with rhetorical cynicism. The stewardship ethic embodied by agriculture is transcended into a cynicism whereby nature is distrusted and elusive. 相似文献

The aim of this study was to establish the influence of weather and pitch conditions on the frequency and nature of rugby injuries. Observers at 26 senior rugby clubs in the Borders District of the Scottish Rugby Union reported all injuries to 1169 (96%) registered players at Saturday home and away matches during the 1993-94 season (August 1993 to April 1994). Weather and pitch conditions at 112 grounds were recorded on 605 occasions; 1268 Borders teams played at these grounds,with 344 injury episodes being sustained. Matches were played in dry weather for three-quarters of these occasions. There was a moderate association between weather and the state of the pitch (Spearman's rank correlation, r = -0.46, P ? 0.001), with heavier pitches occurring in wetter weather. Logistic regression revealed that there were significant month-of-season (P = 0.003), wind strength (P = 0.008) and temperature (P = 0.011) effects on the risk of injury. On four of five occasions when matches were played in a downpour of rain, at least one injury episode occurred. Our results show that the month of the season and the weather may influence the occurrence of rugby injuries, but that the state of the pitch does not. Further studies are required to investigate these factors in more detail. 相似文献

应用WRF-chem模式模拟京津冀地区气溶胶污染对夏季气象条件的影响 总被引：4，自引：0，他引：4
本文利用WRF-chem空气质量模式,模拟研究2006年夏季代表月份7月的气溶胶污染对京津冀地区的温度、风速、PBL高度以及降水量等的影响。模拟结果表明,在气溶胶的直接和间接气候效应的作用下京津冀地区2006年夏季区域平均温度下降了0.19℃、风速升高了0.089m／s、PBL高度下降了34.42m、降水量增加了0.069mm。研究发现,对于污染较重的地区地面10m风速的下降程度显著,而地面2m温度和PBL高度则明显的下降,对于污染较轻的地区地面2m温度和PBL高度有明显的下降,地面10m风速则有明显的上升。此外,由于地形的作用,北京市平原地区的温度和PBL高度的下降量低于山地地区,而风速则相反。 相似文献

艾伟的《风和日丽》以共和国的60年历史变迁为基本写作背景,通过若干主要人物曲折命运的充分展示,对人物复杂深邃的人性世界进行了深入的探究挖掘,而且还甚为成功地刻画塑造出了若干生动丰满、别具人性深度的人物形象。也非常成功地传达出了某种只可意会难以言传的命运感。 相似文献

天气雷达是定量测量降水回波强度的设备,而天气雷达回波强度的定标精度,决定了天气雷达测量降水强度的准确性。713XD多普勒天气雷达的具有不同工作模式,每种工作模式雷达工作参数设置不相同,再加上多普勒信号处理器(包括与之配套使用的数字中频接收机)的算法不同,导致天气雷达回波强度在不同工作模式下测量值不同。采用与工作模式相配套的定标程序,解决了同一回波不同模式观测强度不一致的问题。文章阐述了天气雷达回波强度定标的基本原理,分析了回波强度观测值与理论值产生偏差的原因,通过编程实现了不同工作模式下不同的回波强度定标,并给出了实际的定标曲线。 相似文献
