Abstract We assembled daily precipitation records, initially for 3838 stations, throughout India and ultimately identified 129 stations with reasonably complete records over the period 1910 to 2000. From these we generated annual time series of seven different indices extreme events, including total precipitation, largest 1, 5, 30 day totals, number events above amount that marks 90th, 95th, 97.5th percentiles all at each station. Of 903 (seven variables stations), 114 had a significant...
Water remains an essential ingredient for the rapid population growth taking place in metropolitan Phoenix, Arizona. Depending upon municipality, between 60 and 75% of residential water is used outdoors to maintain nonnative, water‐intensive landscapes swimming pools. Residential use Phoenix should be especially sensitive meteorological climatic variations because strong emphasis on outdoor use. This study explores intraurban spatial sensitivity consumption atmospheric conditions. For 230...
Abstract In this investigation, how annual water use in the city of Phoenix, Arizona, was influenced by climatic variables between 1980 and 2004 is examined. Simple correlation coefficients mean temperature, total precipitation, Palmer hydrological drought index values are +0.55, −0.69, −0.52, respectively, over study period (annual increases with higher lower drought). Multivariate analyses using monthly data indicate that controlled most overall state drought, autumn temperatures,...
Abstract Climate change, grazing practices, timbering activities, and erosional thresholds have been proposed to explain widespread accelerated arroyo erosion near the turn of century in southwestern United States. We analyze morphology potential causes activity Zuni River drainage basin New Mexico; our analyses illustrate linkage between arroyos changes that occurred through time local precipitation patterns. Substantial archival geological evidence confirms dominant downcutting...
The uncertainties associated with global climate models pose substantial hurdles for urban water planning. Despite growing consensus among climatologists that the American Southwest is headed a warmer and drier future, planners in metropolitan Phoenix elsewhere are reluctant to consider long-term change as significant factor increased risk of future scarcity. A new paradigm research planning needed—one based on an assumption uncertainty vision multiple plausible futures, managing risk,...
We investigate trends in extreme precipitation Iran for 1951–2007 using the recently released APHRODITE daily rainfall time series. find that seven different indices of all show an upward trend through study period. The include annual total, number days above a certain threshold, maximum received over period time, one-day precipitation, and with 90th percentile. A principal components analysis reveals one eigenvector explaining much variance this component exhibits strong whole Iran. On...
Air temperatures, relative humidities, and atmospheric carbon dioxide concentrations were measured at a height of 2 m approximate 1.6-km intervals prior to sunrise in the middle afternoon on five days January along number different transects through extended metropolitan area Phoenix, Arizona. Spatially interpolated maps data indicate presence an "urban CO2 dome" that reaches as high 555 ppmv city center decreases value approximately 370 outskirts this time year. Pre-dawn values inside dome...
We assembled data at a 1° latitude by longitude resolution for 285 cells across India and analyzed the seasonal trends in maximum minimum temperature, diurnal temperature range (DTR), cloud cover time period 1931–2002. Significant increases have occurred over Deccan plateau, but general, DTR were not significant except decrease northwest Kashmir summer. The effect of on was expectedly negative most country winter summer seasons with increase Kashmir.
The association between a developing urban heat island and local monthly averaged wind speeds is examined in this investigation. Results from series of statistical analyses show significant increase Phoenix, Arizona during the period rapid development. winds found to be much stronger at 0500 MST than 1400 MST. Increased instability development strong low circulation environment are suggested as probable causes for increased speeds.
Abstract Twenty‐three years of maximum and minimum air temperature data are analysed for selected stations in near Kuwait City, Kuwait. The results a series statistical analyses reveal the general lack well‐developed heat island this rapidly expanding urban area. This finding is stark contrast to identification large islands growing arid‐land cities North America. similarities urban‐rural landscape City environment its close proximity water body suggested as explanations observed temporal...
