Large-scale features and evaluation of the PMIP4-CMIP6 midHolocene simulations
The mid-Holocene (6000 years ago) is a standard time period for the evaluation of the simulated response of global climate models using palaeoclimate reconstructions. The latest...- publication PDF

Graupel and hail terminal velocities: Does a "supercritical" Reynolds Number apply?
This study characterizes the terminal velocities of heavily rimed ice crystals and aggregates, graupel, and hail using a combination of recent drag coefficient and particle bulk...- publication PDF

Budgets for nocturnal VOC oxidation by nitrate radicals aloft during the...
Industrial emissions in Houston, Texas, and along the U.S. Gulf Coast are a large source of highly reactive anthropogenic volatile organic compounds (VOCs), principally alkenes,...- publication PDF

Extrapolating shortwave geostationary satellite imagery of clouds into...
The lack of shortwave (SW, visible, and near-infrared) geostationary satellite data at night results in degradation of many weather forecasts and real-time diagnostic products....- publication PDF

Short-term variability in the ionosphere due to the nonlinear interaction...
Using the thermosphere-ionosphere-mesosphere electrodynamics general circulation model simulations, we investigate the short-term ionospheric variability due to the child waves...- publication PDF

Air parcel trajectory dispersion near the tropical tropopause
Dispersion of backward air parcel trajectories that are initially tightly grouped near the tropical tropopause is examined using three ensemble approaches: "RANWIND," in which...- publication PDF

Improving large-domain convection-allowing forecasts with high-resolution...
Analyses with 20-km horizontal grid spacing were produced from continuously cycling three-dimensional variational (3DVAR), ensemble square root Kalman filter (EnSRF), and...- publication PDF

How often does it really rain?
The perception about whether a place is a nice place to live often depends on how often it rains (or snows). The frequency relates to how dreary the weather appears, and it is...- publication PDF

New particle formation from the oxidation of direct emissions of pine seedlings
Measurements of particle formation following the gas phase oxidation of volatile organic compounds (VOCs) emitted by Scots pine (Pinus sylvestris L.) seedlings are reported....- publication PDF

Observed humidity trends in dry regions contradict climate models
Arid and semi-arid regions of the world are particularly vulnerable to greenhouse gas- driven hydroclimate change. Climate models are our primary tool for projecting the future...- publication PDF

Contrary responses of the Gulf Stream and the Kuroshio to Arctic sea ice loss
The impact on the Gulf Stream and Kuroshio from Arctic sea ice loss is investigated using the Community Climate System Model version 4 (CCSM4) model for their important roles...- publication PDF

A process-based evaluation of the Intermediate Complexity Atmospheric...
The evaluation of models in general is a nontrivial task and can, due to epistemological and practical reasons, never be considered complete. Due to this incompleteness, a model...- publication PDF

Spatiotemporal variability and predictability of relative humidity over West...
Spatial and temporal variability of relative humidity over the West African monsoon (WAM) region is investigated. In particular, the variability during the onset and retreat...- publication PDF

The SOA/VOC/Nox system: An explicit model of secondary organic aerosol formation
Our current understanding of secondary organic aerosol (SOA) formation is limited by our knowledge of gaseous secondary organics involved in gas/particle partitioning. The...- publication PDF

Development and evaluation of a coupled photosynthesis-based gas exchange...
Current land surface schemes used for mesoscale weather forecast models use the Jarvis-type stomatal resistance formulations for representing the vegetation transpiration...- publication PDF
