Atmospheric Wet Deposition in Remote Regions: Benchmarks for Environmental Change
(American Meteorological Society, 2015)recipitation composition was characterized at 14 remote sites between 65°N and 51°S. Anthropogenic sources contributed to non-sea-salt (nss) SO42?, NO3?, and NH4+ in North Atlantic precipitation. Biogenic sources accounted ... -
Chemical Characteristics and Source Analysis of Aerosol Composition over the Bohai Sea and the Yellow Sea in Spring and Autumn
(American Meteorological Society, 2015)he total suspended particulate (TSP) samples over the Bohai Sea and the Yellow Sea were collected during two cruises in spring and autumn in 2012. Concentrations of water-soluble ions {Na+, K+, NH4+, Mg2+, Ca2+, Cl?, NO3 ... -
Explicitly Simulated Electrification and Lightning within a Tropical Cyclone Based on the Environment of Hurricane Isaac (2012)
(American Meteorological Society, 2015)his work analyzes a high-resolution 350-m simulation of the electrification processes within a hurricane in conjunction with available total lightning observations to augment the general understanding of some of the key ... -
Jupiter’s Unearthly Jets: A New Turbulent Model Exhibiting Statistical Steadiness without Large-Scale Dissipation
(American Meteorological Society, 2015)longstanding mystery about Jupiter has been the straightness and steadiness of its weather-layer jets, quite unlike terrestrial strong jets with their characteristic unsteadiness and long-wavelength meandering. The problem ... -
Horizontal Transition of Turbulent Cascade in the Near-Surface Layer of Tropical Cyclones
(American Meteorological Society, 2015)ropical cyclones (TC) consist of a large range of interacting scales from hundreds of kilometers to a few meters. The energy transportation among these different scales?that is, from smaller to larger scales (upscale) or ... -
On the Leading Patterns of Northern Hemisphere Sea Level Pressure Variability
(American Meteorological Society, 2015)he leading patterns of variability of the monthly mean Northern Hemisphere (NH) sea level pressure (SLP) field, as derived from empirical orthogonal teleconnection (EOT) analysis of a 93-yr (1920?2012) record of NOAA?CIRES ... -
Observed and Modeled Warm Rainfall Occurrence and Its Relationships with Cloud Macrophysical Properties
(American Meteorological Society, 2015)bserved and modeled rainfall occurrence from shallow (warm) maritime clouds and their composite statistical relationships with cloud macrophysical properties are analyzed and directly compared. Rain falls from ~25% of warm, ... -
A Potential Problem with the Application of Moist Static Energy in Tropical Cyclone Studies
(American Meteorological Society, 2015)he moist static energy (MSE) is derived from the first law of thermodynamics and has been widely used in tropical cyclone (TC) studies because of its energetic and conventionally recognized conservation properties. This ... -
Subsidence Warming as an Underappreciated Ingredient in Tropical Cyclogenesis. Part I: Aircraft Observations
(American Meteorological Society, 2015)he development of a compact warm core extending from the mid-upper levels to the lower troposphere and related surface pressure falls leading to tropical cyclogenesis (TC genesis) is not well understood. This study documents ... -
Entropy Production and Climate Efficiency
(American Meteorological Society, 2015)arth?s climate system is a heat engine, absorbing solar radiation at a mean input temperature Tin and emitting terrestrial radiation at a lower, mean output temperature Tout < Tin. These mean temperatures, defined as the ... -
Microphysics of Aerodynamic Contrail Formation Processes
(American Meteorological Society, 2015)erodynamic condensation is a result of intense adiabatic cooling in the airflow over aircraft wings and behind propeller blades. Out of cloud, condensation appears as a burstlike fog (jet aircraft during takeoff and landing, ... -
