AbstractA 33-yr climatology of shear lines occurring over the Yangtze–Huai River basin (YHSLs) of eastern China during the mei-yu season (i.e., June and July) of 1981–2013 is examined using the daily ERA-Interim reanalysis data and daily rain gauge observations. Results show that (i) nearly 75% of the heavy-rainfall days (i.e., >50 mm day−1) are accompanied by YHSLs, (ii) about 66% of YHSLs can produce heavy rainfall over the Yangtze–Huai River basin, and (iii) YHSL-related heavy rainfall occurs frequently in the south-central basin. The statistical properties of YHSLs are investigated by classifying them into warm, cold, quasi-stationary, and vortex types based on their distinct flow and thermal patterns as well as orientations and movements. Although the warm-type rainfall intensity is the weakest among the four, it has the highest number of heavy-rainfall days, making it the largest contributor (33%) to the total mei-yu rainfall amounts associated with YHSLs. By comparison, the quasi-stationary type has the smallest number of heavy-rainfall days, contributing about 19% to the total rainfall, whereas the vortex type is the more frequent extreme-rain producer (i.e., >100 mm day−1). The four types of YHSLs are closely related to various synoptic-scale low-to-midtropospheric disturbances—such as the southwest vortex, low-level jets, and midlatitude traveling perturbations that interact with mei-yu fronts over the basin and a subtropical high to the south—that provide favorable lifting and the needed moisture supply for heavy-rainfall production. The results have important implications for the operational rainfall forecasts associated with YHSLs through analog pattern recognition.

This paper focuses on the representation of horses graved on rocks in the Mouro River basin (NW Portugal), an afluent in the south margin of the Minho River. The objectives are the study of its distribution in space, in relation to physical characteristics; the specificity of types of graved horses; the characteristics of the rocks graved by group of horses; the orientation of horses by type and their disposition in the rock compared to other graved motifs.

Homer Norris (1929-2018), a commercial artist by profession and a life-time resident of eastern Parker County, in North-Central Texas, in the South Fork and Clear Fork drainages of the upper Trinity River basin, roamed the landscape from at least 30-50 years ago in search of archeological evidence of Native American use and settlement in the basin. He took and maintained detailed notes, records, and drawings of the sites he found and the artifacts he recovered, as well as pertinent information on the context of finds, including those noted eroding out of stream cut banks and in stream beds of the South Fork and Clear Fork in the Anetta-Aledo areas of Parker County, about 15 miles west of Fort Worth, an area of about 5 miles on a side. This information, made available by his daughter Lanie Garmon of Aledo, Texas, from his archeological investigations is detailed herein, along with a summary of how his investigations contribute to a fuller understanding of the native history of this region of Texas.
