Hydroclimatological time series often exhibit trends. While trend magnitude can be determined with little ambiguity, the corresponding statistical significance, sometimes cited to bolster scientific and political argument, is less certain because significance depends critically on the null hypothesis which in turn reflects subjective notions about what one expects to see. We consider statistical trend tests of hydroclimatological data in the presence of long‐term persistence (LTP). Monte Carlo…

Statistical analysis of hydroclimatic time series: Uncertainty and insights

Analytical methods demonstrate by using analytical methods that the characteristics of temperature series, which appear to be compatible with the LTP hypothesis, imply a dramatic increase of uncertainty in statistical estimation and reduction of significance in statistical testing, in comparison with classical statistics.

Statistical Uncertainty in Hydrometeorological Trend Analyses

This study demonstrates the existence of uncertainty in hydrometeorological trend analyses using historical rainfall from Kenya in East Africa. With respect to the influence of short- and long-term

Innovative Variance Corrected Sen’s Trend Test on Persistent Hydrometeorological Data

Trend detection in observations helps one to identify anthropogenic forces on natural hydrological and climatic systems. Hydrometeorological data are often persistent over time that deviates from the

On the (mis)use of statistical methods in hydro-climatological research

Abstract This paper discusses four areas where, in the author's view, statistical methods are misused in reporting results of hydro-climatological research. They are: (i) the use of the same data set

Trend Identification Simulation and Application

The main purpose of this paper is to provide simulation results and applications of a trend analysis methodology that is not affected from such a restriction.

Deterministic versus stochastic trends: Detection and challenges

[1] The detection of a trend in a time series and the evaluation of its magnitude and statistical significance is an important task in geophysical research. This importance is amplified in climate

Brief Communication: Likelihood of societal preparedness for global change: trend detection

Abstract. Anthropogenic influences on earth system processes are now pervasive, resulting in trends in river discharge, pollution levels, ocean levels, precipitation, temperature, wind, landslides,



Climate change: Detection and its impact on hydrologic design

Controversy regarding origins of the so-called Hurst phenomenon has continued since the first appearance of Hurst's work. There appear to be at least two general mechanisms which might generate

Climate change, Hurst phenomenon, and hydrologic statistics

The intensive research of the recent years on climate change has led to the strong conclusion that climate has ever, through the planet history, changed irregularly on all time scales. Climate

Climate change, the Hurst phenomenon, and hydrological statistics

Abstract The intensive research of recent years on climate change has led to the strong conclusion that climate has always, throughout the Earth's history, changed irregularly on all time scales.

Global warming and the problem of testing for trend in time series data

Simulation evidence is provided to show that the tests for trend detect a deterministic trend in a relatively high percentage of realizations from a wide range of ARMA models, including those obtained for the Teesside temperature datasets.

Modeling persistence in hydrological time series using fractional differencing

The class of autoregressive integrated moving average (ARIMA) time series models may be generalized by permitting the degree of differencing d to take fractional values. Models including fractional

The regional persistence and variability of annual streamflow in the United States

Inference from individual streamflow records can be extremely misleading, even for large samples. One is often tempted to trust information available from a streamflow record rather than to exploit

Evidence for nonstationarity as a physical explanation of the Hurst Phenomenon

Analysis of six precipitation records from the east coast of the United States supports nonstationarity of the mean as a physical explanation of the Hurst phenomenon. One possible mechanism is

Factors affecting the detection of trends: Statistical considerations and applications to environmental data

Detection of long-term, linear trends is affected by a number of factors, including the size of trend to be detected, the time span of available data, and the magnitude of variability and

Statistical Analysis in Climate Research

This chapter discusses statistical concepts in climate research, as well as time series and stochastic processes, and some of the techniques used to estimate covariance functions and spectra.

A generalized mathematical framework for stochastic simulation and forecast of hydrologic time series

A generalized framework for single‐variate and multivariate simulation and forecasting problems in stochastic hydrology is proposed. It is appropriate for short‐term or long‐term memory processes and
