Rotach 2004 ), especially in terms of the local circulations and their impact on air quality and local microclimate. The purpose of this study is to look at a very specific surface type in a complex terrain environment (the river), and the exchanges between the river surface and the atmosphere. Rivers have an important role in the atmospheric environment of their surroundings, in many cases. They may induce local circulations ( Zhong and Takle 1992 ; Oliveira and Fitzjarrald 1994 ; Silva Dias et al

climatology and atmospheric studies. Evaluation of the information provided by reanalyses (e.g., on snow characteristics) may therefore be useful for various users. North-flowing Russian rivers are responsible for the bulk of freshwater supplied to the Arctic Ocean. The regime of freshwater inflow is an important component of coastal ocean dynamics. Recent studies demonstrated an increase of northern river runoff, especially in winter and spring seasons (e.g., Serreze et al. 2003 ; Yang et al. 2003

1. Introduction The higher air temperature in a city than in its surrounding rural area, which is known as the urban heat island (UHI), can generate or modify local circulations in the city and its vicinity. When the synoptic forcing is weak, a local circulation can develop in regions where a temperature contrast exists, such as between sea and land, lake and land, river and land, and mountain and valley. Besides well-known local circulations such as sea-breeze and valley-breeze circulations, a

1. Introduction Hydrologic extremes of heavy precipitation and severe drought stress water resources and damage communities in the Red River basin, located in the south-central United States. For example, the summer of 2011 was the third driest summer in Oklahoma state history and the driest in Texas history since records began in 1895. These states suffered great losses from prolonged drought conditions, with U.S. Drought Monitor category D4 (exceptional drought) applying to almost all of

Introduction In the winter of 1989–90, a Winter Visibility Study (WVS) was conducted in the region around the Grand Canyon of the Colorado River to determine the impact on visibility within Grand Canyon National Park of pollution plumes from the Navajo Generating Station, a 2300 MW coal-fired power plant located at Page, Arizona. An extensive network of 10-m meteorological towers was deployed throughout the Grand Canyon area of southern Utah and northern Arizona as part of this study. The wind

1. Introduction This research is a part of a larger project focused on the historical characteristics and projected future changes of precipitation variability in the Colorado River basin, which includes a quantitative comparison between the observed precipitation variability and that simulated by general circulation models (GCMs) for the historical period 1950–99. Such a long-term trend or variability analysis requires the homogeneity of the datasets to be evaluated. Homogeneous climate data
