RISPenalized Maximal F Test for Detecting Undocumented Mean Shift without Trend Change
Publisher: American Meteorological Society
Abstract: In this study, a penalized maximal F test (PMFT) is proposed for detecting undocumented mean shifts that are not accompanied by any sudden change in the linear trend of time series. PMFT aims to even out the uneven ...
Accounting for Autocorrelation in Detecting Mean Shifts in Climate Data Series Using the Penalized Maximal t or F Test
Publisher: American Meteorological Society
Abstract: This study proposes an empirical approach to account for lag-1 autocorrelation in detecting mean shifts in time series of white or red (first-order autoregressive) Gaussian noise using the penalized maximal t test or the ...

Spatial–Temporal Structures of Trend and Oscillatory Variabilities of Precipitation over Northern Eurasia
Publisher: American Meteorological Society
Abstract: Combinations of statistical analyses including principal component analysis, and uni- and multivariate singular spectrum analyses, were carried out to characterize the spatial?temporal structures of trend and interannual ...
Adverse-Weather Trends in the Canadian Arctic
Publisher: American Meteorological Society
Abstract: This study provides an assessment of changes in the occurrence frequency of four types of adverse-weather (freezing precipitation, blowing snow, fog, and low ceilings) and no-weather (i.e., no precipitation or visibility ...
Interannual Variability of Precipitation in an Ensemble of AMIP Climate Simulations Conducted with the CCC GCM2
Publisher: American Meteorological Society
Abstract: In this paper log?linear analysis and analysis of variance methods were used to analyze the interannual variability and potential predictability of precipitation as simulated in an ensemble of six 10-yr Atmospheric Model ...
Trends of Atlantic Wave Extremes as Simulated in a 40-Yr Wave Hindcast Using Kinematically Reanalyzed Wind Fields
Publisher: American Meteorological Society
Abstract: In this study, seasonal extremes of wave height in the North Atlantic are analyzed. The analysis is based on a 40-yr (1958?97) numerical wave hindcast using an intensive kinematic reanalysis of wind fields. Changes in the ...
Changes of Extreme Wave Heights in Northern Hemisphere Oceans and Related Atmospheric Circulation Regimes
Publisher: American Meteorological Society
Abstract: This study assesses trends in seasonal extremes (90- and 99-percentiles) of Significant Wave Height (SWH) in the North Atlantic and the North Pacific, as simulated in a 40-yr global wave hindcast using the National Centers ...
Homogenization and Trend Analysis of the 1958–2016 In Situ Surface Solar Radiation Records in China
Publisher: American Meteorological Society
Abstract: AbstractThis paper presents a method to homogenize China?s surface solar radiation (SSR) data and uses the resulting homogenized SSR data to assess the SSR trend over the period 1958?2016. Neighboring surface sunshine ...
Penalized Maximal t Test for Detecting Undocumented Mean Change in Climate Data Series
Publisher: American Meteorological Society
Abstract: In this paper, a penalized maximal t test (PMT) is proposed for detecting undocumented mean shifts in climate data series. PMT takes the relative position of each candidate changepoint into account, to diminish the effect ...
