Time trends and persistence in European temperature anomalies

چکیده

This paper looks at the level of persistence in temperature anomalies series 114 European cities. Once this has been identified, time trend coefficients are estimated and results indicate that most examined display positive trends, supporting thus climate warming. Moreover, obtained confirm hypothesis long-memory behaviour cannot be neglected study series, changing, therefore, effect global

Time Series Analysis of Global Temperature Distributions: Identifying and Estimating Persistent Features in Temperature Anomalies∗

We analyze a time series of global temperature anomaly distributions to identify and estimate persistent features in climate change. In our study, temperature densities, obtained from globally distributed data over the period from 1850 to 2012, are regarded as a time series of functional observations that are changing over time. We employ a formal test for the existence of functional unit roots...

Trends in hemispheric warm and cold anomalies

Using a spatial percentile approach, we explore the magnitude of temperature anomalies across the Northern and Southern Hemispheres. Linear trends in spatial percentile series are estimated for 1881–2013, the most recent 30 year period (1984–2013), and 1998–2013. All spatial percentiles in both hemispheres show increases from 1881 to 2013, but warming occurred unevenly via modification of cold ...

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Assessment of temperature anomalies between present time and cold periods of Plio-Pleistocene using geomorphic indicators (case study: Kazab-Yazd)

Climate changes and remained geomorphic evidences due to the changes has been interested by geomorphologists in the world. Different researches have shown that world climate has been changed successively in Pleistocene so that with decreasing in temperature and probably increasing in precipitation, glaciers has been progressed and with increasing in temperature and decreasing in precipitation, ...

Power-law persistence and trends in the atmosphere: a detailed study of long temperature records.

We use several variants of the detrended fluctuation analysis to study the appearance of long-term persistence in temperature records, obtained at 95 stations all over the globe. Our results basically confirm earlier studies. We find that the persistence, characterized by the correlation C(s) of temperature variations separated by s days, decays for large s as a power law, C(s) approximately s(...
