RISCondensation Heat Transfer in Ultracompact Minichannel Heat Exchangers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To improve condensation heat transfer performance in a variety of systems, reduced channel sizes are used. However, few studies have been performed on complete heat exchangers. Hence, condensation heat transfer coefficients ...
Measurements of Boundary Layer Profiles with In Situ Sensors and Doppler Lidar
Publisher: American Meteorological Society
Abstract: A new in situ measurement system and lidar processing algorithms were developed for improved measurements of boundary layer profiles. The first comparisons of simultaneous Doppler lidar?derived profiles of the key turbulence ...
Radiative and Microphysical Characteristics of Deep Convective Systems in the Tropical Western Pacific
Publisher: American Meteorological Society
Abstract: The radiative and microphysical characteristics of 17 precipitating systems observed by the Tropical Rainfall Measuring Mission (TRMM) satellite over Manus, Papua New Guinea, and Nauru Island are modeled. These cases ...
Factors Limiting Convective Cloud-Top Height at the ARM Nauru Island Climate Research Facility
Publisher: American Meteorological Society
Abstract: Cumulus congestus clouds, with moderate shortwave albedos and cloud-top temperatures near freezing, occur fairly often in the Tropics. These clouds may play an important role in the evolution of the Madden?Julian oscillation ...
Turbulence Measurements with the CIRES Tethered Lifting System during CASES-99: Calibration and Spectral Analysis of Temperature and Velocity
Publisher: American Meteorological Society
Abstract: Finescale temperature and velocity measurements with multiple vertically spaced cold-wire and hot-wire sensors on the Cooperative Institute for Research in the Environmental Sciences (CIRES) tethered lifting system (TLS) ...
A Statistical Description of Small-Scale Turbulence in the Low-Level Nocturnal Jet
Publisher: American Meteorological Society
Abstract: The probability density function (PDF) and spatial statistics of both the energy dissipation rate ? and the temperature structure constant C2T are determined for the shear region of a nocturnal jet. The PDF of ? and C2T ...
Diurnal Cloud and Thermodynamic Variations in the Stratocumulus Transition Regime: A Case Study Using In Situ and Remote Sensors
Publisher: American Meteorological Society
Abstract: Radiosonde, in situ, and surface-based remote sensor data from the Atlantic Stratocumulus Transition Experiment are used to study the diurnal cycle of cloud and thermodynamic structure. A cloud layer and decoupled subcloud ...
Radiative Impacts of Anvil Cloud during the Maritime Continent Thunderstorm Experiment
Publisher: American Meteorological Society
Abstract: In this study the radiative impact of three separate cirrus anvil systems that occurred during the Maritime Continent Thunderstorm Experiment is investigated. Retrievals of microphysical cloud properties and an independent ...
Evaluation of Power Transmission Lines Hardening Scenarios Using a Machine Learning Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The power transmission infrastructure is vulnerable to extreme weather events, particularly hurricanes and tropical storms. A recent example is the damage caused by Hurricane Maria (H-Maria) in the archipelago of Puerto ...
Investigation of Regional and Seasonal Variations in Marine Boundary Layer Cloud Properties from MODIS Observations
Publisher: American Meteorological Society
Abstract: To aid in understanding the role that marine boundary layer (MBL) clouds play in climate and assist in improving their representations in general circulation models (GCMs), their long-term microphysical and macroscale ...
