A theory for the retrieval of virtual temperature from winds, radiances and the equations of fluid dynamics [PDF]

, 1986
A technique to deduce the virtual temperature from the combined use of the equations of fluid dynamics, observed wind and observed radiances is described.

Multistep variational data assimilation: important issues and a spectral approach

Tellus: Series A, Dynamic Meteorology and Oceanography, 2016
In this paper, two important issues are raised for multistep variational data assimilation in which broadly distributed coarse-resolution observations are analysed in the first step, and then locally distributed high-resolution observations are analysed ...

Simulation of regional rainfall observation using urban surveillance camera networks

Environmental Research Letters
Widespread surveillance cameras show excellent potential for high spatial and temporal resolution rainfall observation. As the accuracy of surveillance camera-based rain gauges (SRGs) continues to improve, surveillance camera-based rainfall observation ...

Data management and analysis with WRF and SFIRE

, 2012
We introduce several useful utilities in development for the creation and analysis of real wildland fire simulations using WRF and SFIRE. These utilities exist as standalone programs and scripts as well as extensions to other well known software.

Utilization of high resolution short range weather forecast for agro advisory services

Journal of Agrometeorology, 2010
Agriculture is heavily weather dependent in India. The economy of the country is largely synchronized to the success of agriculture every year, as it contributes nearly 25% to gross domestic product (GDP). Farming community, planners and line department

Observation and backward trajectory of an inertio-gravity wave in the lower stratosphere [PDF]

Annales Geophysicae, 2001
A Doppler lidar observation of an inertio-gravity wave in the mid-latitude lower stratosphere is presented. The wave packet characteristics (vertical and horizontal wavenumbers, intrinsic and apparent frequencies) are inferred from the analysis ...

Raindrop Size Distributions and Rain Characteristics Observed by a PARSIVEL Disdrometer in Beijing, Northern China

Remote Sensing, 2019
Fourteen-month precipitation measurements from a second-generation PARSIVEL disdrometer deployed in Beijing, northern China, were analyzed to investigate the microphysical structure of raindrop size distribution and its implications on polarimetric radar

Toward the Standardization of Mesoscale Meteorological Networks

Journal of Atmospheric and Oceanic Technology, 2020
AbstractAlthough they share many common qualities in design and operation, mesonetworks across the United States were established independently and organically over the last several decades. In numerous instances, the unique ways each network matured and developed new protocols has led to important lessons learned. These experiences have been shared in

Utilization of satellite data in mesoscale modeling of severe weather [PDF]

The Visible Infrared Spin Scan Radiometer Atmospheric Sounder (VAS) data were used to model the 36 hour cyclogenesis period over the Pacific Ocean. Various combinations of VAS data, conventional radiosonde data, and gridded data from the National Weather

Impacts of precipitation uncertainty on hydrological ensemble simulations over the Ganjiang River basin

Journal of Hydrology: Regional Studies
Study region: The Ganjiang River basin (113°−117°E, 24°−30°N; 83,374 km2) is a large watershed with complex topography in the Poyang Lake basin in Jiangxi province, China. Study focus: This study evaluates three quantitative precipitation estimates (QPEs)
