Simulation Uncertainty of Near-Surface Wind Caused by Boundary Layer Parameterization Over the Complex Terrain

open access: yesFrontiers in Energy Research, 2020
Accurate prediction of near-surface wind based on numerical weather prediction models is essential to promote efficient wind energy harvesting. In this study, the performances of different Boundary Layer (BL) schemes in Weather Research and Forecasting ...

A spatial analysis of multivariate output from regional climate models [PDF]

open access: yes, 2011
Climate models have become an important tool in the study of climate and climate change, and ensemble experiments consisting of multiple climate-model runs are used in studying and quantifying the uncertainty in climate-model output.

Changes in the Seasonally Frozen Ground Over the Eastern Qinghai-Tibet Plateau in the Past 60 Years

open access: yesFrontiers in Earth Science, 2020
The Qinghai-Tibet Plateau (QTP) has the largest extent of high altitude permafrost at the middle and low latitudes in northern hemisphere and is surrounded by dozens of seasonally frozen ground.

Long-term temperature trends and variability on Spitsbergen: the extended Svalbard Airport temperature series, 1898–2012 [PDF]

open access: yesPolar Research, 2014
One of the few long instrumental records available for the Arctic is the Svalbard Airport composite series that hitherto began in 1911, with observations made on Spitsbergen, the largest island in the Svalbard Archipelago.

A continuous latitudinal energy balance model to explore non-uniform climate engineering strategies [PDF]

open access: yes, 2019
In order to investigate the effects of solar radiation management (SRM) technologies for climate engineering, an analytical model describing the main latitu8 dinal dynamics of the Earth’s climate with closed-loop control has been developed.

Climate Predictions: The Chaos and Complexity in Climate Models [PDF]

open access: yesAdvances in Meteorology, 2014
Some issues which are relevant for the recent state in climate modeling have been considered. A detailed overview of literature related to this subject is given. The concept in modeling of climate, as a complex system, seen through Gödel’s theorem and Rosen’s definition of complexity and predictability is discussed. Occurrence of chaos in computing the

Towards improved and more routine Earth system model evaluation in CMIP [PDF]

open access: yesEarth System Dynamics, 2016
The Coupled Model Intercomparison Project (CMIP) has successfully provided the climate community with a rich collection of simulation output from Earth system models (ESMs) that can be used to understand past climate changes and make projections and ...

Underestimating Internal Variability Leads to Narrow Estimates of Climate System Properties [PDF]

open access: yes, 2019
Probabilistic estimates of climate system properties often rely on the comparison of model simulations to observed temperature records and an estimate of the internal climate variability.

Evaluation of Climate Models [PDF]

open access: yes, 2014
Climate models have continued to be developed and improved since the AR4, and many models have been extended into Earth System models by including the representation of biogeochemical cycles important to climate change. These models allow for policy-relevant calculations such as the carbon dioxide (CO2) emissions compatible with a specified climate ...

Tropospheric Warming Over The Past Two Decades

open access: yesScientific Reports, 2017
Satellite temperature measurements do not support the recent claim of a “leveling off of warming” over the past two decades. Tropospheric warming trends over recent 20-year periods are always significantly larger (at the 10% level or better) than model ...
