DOI: 10.1002/env.2665
Abstract: Statistical methods are required to evaluate and quantify the uncertainty in environmental processes, such as land and sea surface temperature, in a changing climate. Typically, annual harmonics are used to characterize the variation in the… read more here.

DOI: 10.1007/s00477-017-1427-7
Abstract: As a supplementary method to the conventional flood frequency analysis based on annual peak flows, we propose an approach in this paper to infer the flood frequency distribution on quarterly and semi-annual time scale, which… read more here.

DOI: 10.1016/j.jdent.2020.103522
Abstract: OBJECTIVE The aim of this randomised non-inferiority clinical trial was to compare the effectiveness of semi-annual (every six months) applications of 25% silver nitrate (AgNO3) solution followed by 5% sodium fluoride (NaF) to semi-annual applications… read more here.

DOI: 10.5194/angeo-2021-27
Abstract: Abstract. Seasonal features of geomagnetic activity and their solar wind-interplanetary drivers are studied using more than 5 solar cycles of geomagnetic activity and solar wind observations. This study involves a total of 1239 geomagnetic storms… read more here.

DOI: 10.5194/angeo-39-255-2021
Abstract: Abstract. Ground-based observations show a phase shift in semi-annual variation of excited hydroxyl ( OH∗ ) emissions at mid-latitudes (43 ∘ N) compared to those at low latitudes. This differs from the annual cycle at… read more here.
