O objetivo desse trabalho foi analisar a possibilidade de tendências climáticas utilizando dados precipitação pluviométricos na bacia hidrográfica Capibaribe, do estado Pernambuco. Foi utilizada uma série histórica quarenta e cinco anos (552 meses) entre os 1973 2018, obtida no site da Agência Pernambucana Águas Climas - APAC. A análise baseada em apenas um posto pluviométrico. Os que apresenta...
Abstract Despite the increased frequency of extreme climate events including their significance in Nepal's socio-economy, studies have seldom considered extremes, and even fewer them combination with temperature precipitation. This study aimed at examining trend variables Gandaki Province, Nepal. Daily precipitation data five stations between 1990 2020 were analyzed. Modified Mann–Kendall Sen's...
Based on the Mann-Kendall test and Sen’s slope method, this study investigates monthly, seasonal, annual sea surface temperature (SST) trends in coastal area of Hai Phong (West Tonkin Gulf) based measurements at Hon Dau Station from 1995 to 2020. The results show a warming trend 0.02°C/year for period 1995-2020 (significant level α = 0.1) 0.093°C/year 2008-2020 0.05). monthly SSTs June Septembe...
BACKGROUND The recently launched Pneumo Rischio eHealth project, which consists of an app, a website, and social networking activity, is aimed at increasing public awareness of invasive pneumococcal disease (IPD). The launch of this project was prompted by the inadequate awareness of IPD among both laypeople and health care workers, the heavy socioeconomic burden of IPD, and the far from optima...
This paper presents an analysis of the annual precipitation observed by a network 30 rain gauges in Iraq over 65-year period (1941–2005). The simulated from 18 climate models CMIP5 project is investigated same area and time window. Mann–Kendall test used to assess strength significance trends (if any) both simulations observations. Several exploratory techniques are identify similarity (or disa...
Abstract Temperature variability may have direct and indirect impacts on the environments of Accra Kumasi Metropolises in Ghana. This study analysed temperature trends both cities using in-situ measurements from one meteorological station 1986 to 2015. The indices were computed RClimdex package Expert Team Climate Change Detection Monitoring Indices (ETCCDMI). time series was pre-whitened befor...
به لحاظ اهمیت آب های سطحی و کاربرد آن ها در صنایع مختلف، کشاورزی، مصارف شرب و غیره، نیاز است خشکسالی رودخانه ای و یا هیدرولوژیکی به دقت بررسی گردد. بدین منظور شاخص های مختلفی ارائه گردیده است که در میان آن ها شاخص خشکسالی هیدرولوژیکی sdi، تنها با به کارگیری داده های دبی رودخانه می تواند تخمین خوبی از خشکسالی هیدرولوژیکی را ارائه دهد. در این تحقیق با استفاده از داده های دبی روزانه 18 ایستگاه موج...
Climatic parameters in time and space scales of change are for many reasons of Changes and how they should be based on observations using a statistical method to be determined. Analysis of the most widely used statistical methods that assess potential climate change on hydrological time series, such series of precipitation, temperature and flow rate used. This study of 11 synoptic,rain gage and...
