Ozone exchange within and above an irrigated Californian orchard

Tellus: Series B, Chemical and Physical Meteorology, 2020
In this study, the canopy effects on the vertical ozone exchange within and above Californian orchard are investigated. We examined the comprehensive dataset obtained from the Canopy Horizontal Array Turbulence Study (CHATS).

Update of upper level turbulence forecast by reducing unphysical components of topography in the numerical weather prediction model

Geophysical Research Letters, 2016
On 2 November 2015, unrealistically large areas of light‐or‐stronger turbulence were predicted by the WRF‐RAP (Weather Research and Forecast Rapid Refresh)‐based operational turbulence forecast system over the western U.S. mountainous regions, which were

Statistical Characteristics of Mesoscale Convective Systems Initiated over the Tibetan Plateau in Summer by Fengyun Satellite and Precipitation Estimates

Remote Sensing, 2021
In order to investigate the key characteristics of mesoscale convective systems (MCSs) initiated over the Tibetan Plateau (TP) in recent years and the main differences in circulation and environmental factors between different types of MCSs, an automatic

Occurrence of polar stratospheric clouds at Kiruna [PDF]

Annales Geophysicae, 1999
Polar stratospheric clouds (PSCs) are often observed in the Kiruna region in northern Sweden, east of the Scandinavian mountain range, during wintertime. PSC occurrence can be detected by ground-based optical instruments.

Surface winds in the Euro-Mediterranean area: the real resolution of numerical grids [PDF]

Annales Geophysicae, 2004
Surface wind is a variable of great importance in forcing marine waves and circulations, modulating surface fluxes, etc. Surface wind defined on numerical grids is currently used in forecast-analysis, as well as in climatology. Gridded fields, however,

African dust outbreaks over the Mediterranean Basin during 2001–2011: PM 10 concentrations, phenomenology and trends, and its relation with synoptic and mesoscale meteorology

, 2012
. The occurrence of African dust outbreaks over the whole Mediterranean Basin has been studied on an 11-yr period (2001–2011). In order to evaluate the impact of such mineral dust outbreaks on ambient concentrations of particulate matter, PM10 data from ...

How Are Tornadic Supercell Soundings Significantly Different From Nearby Baseline Environments?

Geophysical Research Letters, 2023
This study explores how tornadic supercell soundings significantly differ from the same‐location and same‐hour baseline environment soundings, sampled from the days prior to or following the event. Permutation testing is used to identify whether sounding‐
