1 Abstract-The present paper presents an overview of the main characteristics of a novel kind of solar thermal application called solar chimney power plant. It is a technology of electric power generation using solar energy by employing basic physics that when air is heated it rises. The created updraft can be used to turn a turbine placed at an appropriate position within a tall chimney to gen...

Abstract. Cold-air outbreaks (CAOs) are characterized by extreme air–sea energy exchanges and low-level convective clouds over large areas in the high-latitude oceans. As such, CAOs an important component of Earth's climate system. The Marine Boundary Layer Experiment (COMBLE) deployment US Department Energy Atmospheric Radiation Measurement (ARM) Mobile Facility (AMF) provided first comprehens...

Abstract When directly assimilating radar data within a variational framework using hydrometeor mixing ratios ( q ) as control variables (CVq), the gradient of cost function becomes extremely large when background ratio is close to zero. This significantly slows down minimization convergence and makes assimilation radial velocity other observations ineffective because dominance reflectivity obs...

The mechanism of convection initiation (CI) over Ili River Valley (IRV) in Xinjiang, Northwest China, was investigated based on both weather stations and radar observations Weather Research Forecasting (WRF) model simulation. Observations showed that many CIs occurred repeatedly, most them underwent significant intensification size intensity, eventually formed an extreme rainfall-producing meso...
