Long-term temperature changes in Sicily, Southern Italy

Unravelling links between squid catch variations and biophysical mechanisms in South African waters

“…A bowl-shaped (dome-shaped) cumulative sum curve describes an overall increasing (declining) trend (Briceno and Boyen, 2010). The cumulative sums technique has increasingly been used to determine underlying features of environmental timeseries including long-term Chl-a at the interannual scale (McQuatters-Gollop et al, 2008;Raitsos et al, 2014;Tilstone et al, 2015;Liuzzo et al, 2017;Gittings et al, 2018;Kizenga et al, 2021).…”

Homogenization of instrumental time series of air temperature in Central Italy (1930-2015)

“…The Annual Bulletin on the Climate in WMO Region VI (DWD 2011) showed the trend analysis map for annual temperatures (1951−2011) and re vealed that, in the region of interest (central-southern Italy), the trends were greater than 0.3°C decade −1 . Finally, Liuzzo et al (2017) investigated the long-term temperature changes in Sicily during the 1924− 2013 period and indicated that at some sites, the maximum temperature had a positive trend of 0.5°C decade −1 .

Analyzing and comparing complex environmental time series using a cumulative sums approach

“…To overcome these obstacles, some authors have used the cumulative sums method (Cusum, [7]) to analyze time series. Cusum charts and analysis are well established in the field of industrial process control ([[8], [9], [10]]) and more recently have gained popularity in environmental sciences, including aquatic biology ([11,12]), biogeochemistry ([13,14]), climate change ([[15], [16], [17]]), and in commercial software for time series analysis ([18]).…”
