TLDR
This study aims to provide a common basis for CPM climate simulations by giving a holistic review of the topic, and presents the consolidated outcome of studies that addressed the added value of CPMClimate simulations compared to LSMs.Abstract:
Regional climate modeling using convection-permitting models (CPMs; horizontal grid spacing 10 km). CPMs no longer rely on convection parameterization schemes, which had been identified as a major source of errors and uncertainties in LSMs. Moreover, CPMs allow for a more accurate representation of surface and orography fields. The drawback of CPMs is the high demand on computational resources. For this reason, first CPM climate simulations only appeared a decade ago. In this study, we aim to provide a common basis for CPM climate simulations by giving a holistic review of the topic. The most important components in CPMs such as physical parameterizations and dynamical formulations are discussed critically. An overview of weaknesses and an outlook on required future developments is provided. Most importantly, this review presents the consolidated outcome of studies that addressed the added value of CPM climate simulations compared to LSMs. Improvements are evident mostly for climate statistics related to deep convection, mountainous regions, or extreme events. The climate change signals of CPM simulations suggest an increase in flash floods, changes in hail storm characteristics, and reductions in the snowpack over mountains. In conclusion, CPMs are a very promising tool for future climate research. However, coordinated modeling programs are crucially needed to advance parameterizations of unresolved physics and to assess the full potential of CPMs.read more

The future intensification of hourly precipitation extremes
TL;DR: In this paper, the authors used observations and high-resolution modeling to show that rainfall changes related to rising temperatures depend on the available atmospheric moisture, and that the scaling rates between extreme precipitation and temperature are strongly dependent on the region, temperature, and moisture availability.

TL;DR: In this paper, a comprehensive evaluation of 22 gridded (quasi-)global (sub-)daily precipitation (P) datasets for the period 2000-2016 was conducted, and 13 non-gauge-corrected P datasets were evaluated using daily P gauge observations.

Observed heavy precipitation increase confirms theory and early models
Erich M. Fischer,Reto Knutti +1 more
TL;DR: The authors used the intensification of heavy precipitation as a counterexample, where seemingly complex and potentially computationally intractable processes manifest themselves to first order in simple ways: heavy precipitation intensification is now emerging in the observed record across many regions of the world.

TL;DR: In this paper, the authors present results from a high-resolution climate change simulation that permits convection and resolves mesoscale orography at 4-km grid spacing over much of North America using the Weather Research and Forecasting (WRF) model.

TL;DR: In this article, the authors consider the issues of bias correction and make recommendations for research to overcome model biases, and conclude that bias correction cannot overcome major model errors, and naive application might result in ill-informed adaptation decisions.

General circulation experiments with the primitive equations
TL;DR: In this article, an extended period numerical integration of a baroclinic primitive equation model has been made for the simulation and the study of the dynamics of the atmosphere's general circulation, and the solution corresponding to external gravitational propagation is filtered by requiring the vertically integrated divergence to vanish identically.
