The Persistent Cold-Air Pool Study (PCAPS) was conducted in Utah's Salt Lake valley from 1 December 2010 to 7 February 2011. The field campaign's primary goal was to improve understanding of the physical processes governing the evolution of multiday cold-air pools (CAPs) that are common in mountain basins during the winter. Meteorological instrumentation deployed throughout the Salt Lake valley provided observations of the processes contributing to the formation, maintenance, and destruction of…

The Weather Research and Forecasting (WRF) model is used to simulate a persistent cold air pool (CAP) episode observed in December 2010 during the Persistent Cold Air Pool Study (PCAPS) field

Dynamically Induced Displacements of a Persistent Cold-Air Pool

We examine the influence of a passing weather system on a persistent cold-air pool (CAP) during the Persistent Cold-Air Pool Study in the Salt Lake Valley, Utah, USA. The CAP experiences a sequence

Observational case study of a persistent cold pool and gap flow in the Columbia River Basin

Persistent cold pools form as layers of cold stagnant air within topographical depressions mainly during wintertime when the near-surface air cools and/or the air aloft warms and daytime surface

Synoptic to Microscale Processes Affecting the Evolution of a Cold-Air Pool in a Northern New England Forested Mountain Valley

The formation of katabatic winds and pooling of cold air in mountain valleys impact air quality, precipitation type, and local ecosystem functions. Much is still poorly understood about the

Confronting Uncertainties of Simulated Air Pollution Concentrations during Persistent Cold Air Pool Events in the Salt Lake Valley, Utah.

The CMAQ model is used to simulate the gaseous and particulate species for 1 month in January 2011 during the Persistent Cold Air Pool Study (PCAPS) in the Salt Lake Valley, Utah and results indicate that the temporal variability associated with the elevated NOx and PM2.5 concentrations was captured by the model.

Long‐term evolution of cold air pools over the Madrid basin

Cold air pools (CAPs) are one of the most severe weather conditions experienced across many basins worldwide, related to episodes of extreme cold temperatures, poor air quality, and disruption of

Turbulent Fluxes and Pollutant Mixing during Wintertime Air Pollution Episodes in Complex Terrain.

Observational data is presented to quantify the turbulent mixing during two CAP episodes in Utah's Salt Lake Valley during February of 2004 to indicate that two distinct types of mixing scenarios occur depending on whether the CAP is dry or cloudy.

Multi‐day valley cold‐air pools in the western United States as derived from NARR

Valleys can trap cold air to form Valley Cold Pools (VCPs). Characterized by stable stratification and weak winds, VCPs, especially those that last over multiple days, can produce adverse effects

A short climatological study of cold air pools and drainage flows in small valleys

This paper uses detailed observations from the COLd air Pooling EXperiment (COLPEX) to study the frequency and characteristics of cold air pooling in a small‐scale valley typical of much of the

Measurement and modelling of temperature cold pools in the Cerdanya valley (Pyrenees), Spain

The Cerdanya valley in northeast Spain experiences intense cold air pooling which decouples the valley atmosphere from the regional circulation, especially in winter. This makes air temperature
