Agro-Meteorological Trends of Recent Climate Development in Khorezm and Implications for Crop Production

摘要: The extremely continental climate in the inner Aral Sea Basin is characterized by a high annual temperature amplitude, and constantly very low ­precipitation. Climate change Khorezm region, district of Uzbekistan ­dominated extensive irrigation agriculture, manifest increases, especially during winter period (40-year record). 10-year average ­summer temperatures 1981–1990 was 0.2–0.5°C above long-term 1930–1990. Time series agro-meteorological parameters based on data (air soil temperature, relative humidity, wind speed, precipitation, radiation) three meteorological stations revealed (a) air supporting good growing conditions for cotton, rice, wheat, sorghum, maize; (b) comparatively cotton production; (c) no negative impact regional water demands yet. Moderate spatial variability observed between central system, at its southern ­margin to desert, desert itself (represented Urgench, Khiva, Tuyamuyun, respectively).
