Subjects: Fresh Water Studies, Geochemistry, Hydrology, Meteorology

The Lake Suigetsu sediment cores exemplify a high-quality archive of palaeoclimatic change in East Asia during the past 150 ka. Robust interpretation of stable isotope-based proxy reconstructions from the Suigetsu cores can be aided by a greater understanding of the factors affecting the isotope composition of the lake and how it relates to that of precipitation. Here we use extended contemporary [...]

360-day to Gregorian calendar climate model output conversion

Jonny Williams

Published: 2023-07-05
Subjects: Climate, Earth Sciences, Meteorology, Physical Sciences and Mathematics

Data from some climate model simulations is in a 360 days per year format, that is, every month is 30 days long. The main reason for this is analytical convenience in creating seasonal, annual and multi-annual means which are an integral part of climate model development and evaluation. This work illustrates a method to convert daily-mean, 360-day calendar climate model data into 'real', [...]

Global 1km Land Surface Parameters for Kilometer-Scale Earth System Modeling

Assessment of simulations of a polar low with the Canadian Regional Climate Model

Marta Moreno Ibáñez, René Laprise, Philippe Gachon

Published: 2023-04-14
Subjects: Atmospheric Sciences, Meteorology

Polar lows (PLs), which are intense maritime polar mesoscale cyclones, are associated with severe weather conditions. Due to their small size and rapid development, PL forecasting remains a challenge. Convection-permitting models are adequate to forecast PLs since, compared to coarser models, they provide a better representation of convection as well as surface and near-surface processes. A PL [...]

Humanity is modifying the atmospheric water cycle, via land use, climate change, air pollution, and weather modification. Given the implications of this, we present a theoretical framing of atmospheric water as an economic good. Historically, atmospheric water was tacitly considered a ‘public good’ since it was neither actively consumed (rival) nor controlled (exclusive). However, given [...]
