Transport pathways of air originating in the uppertropospheric Asian monsoon anticyclone are investigated based on three-dimensional trajectories. The Asian monsoon anticyclone emerges in response to persistent deep convection over India and southeast Asia in northern summer, and this convection is associated with rapid transport from the surface to the upper troposphere and possibly into the s...

Transportation is generally perceived as a catalyst for economic development. This has been highlighted in previous studies. However, less attention has been paid to examine the relationship between economy and transport demand by exploring spatially cross-sectional data, especially for countries with significant regional economic imbalance, like China. In this article, we assess the economic i...

Ozone transport has an important effect on the local ozone concentrations. In this paper, we model the California State and the Eastern States of America ozone transport as complex networks to understand large-scale dynamics. California has a complex ozone transport due to geomorphology and is divided into 15 air basins to manage air pollution. Unlike California, the ozone transport in the East...

A simple model has been constructed for microcomputer (PC) simulations involving basic cardiopulmonary principles of oxygen transport. Students can change parameters such as metabolic rate, blood hemoglobin concentration, barometric pressure, air composition, etc., and study parameter effects on blood gas concentrations and partial pressures. An important feature of the model program is that th...

Many sites in the densely populated Indo-Gangetic Plain (IGP) frequently exceed the national ambient air quality standard (NAAQS) of 100 μg m for 24 h average PM10 and 60 μg m for 24 h average PM2.5 mass loadings, exposing residents to hazardous levels of particulate matter (PM) throughout the year. We quantify the contribution of long-range transport to elevated PM levels and the number of exc...

OBJECTIVE Transportation, whether by air or ground, exposes the injured patient to mechanical shocks and vibrations. These forces and their hazardous potential remain largely unknown. The purpose of this study was to identify, characterize, and compare the forces generated during patient transport in helicopter and ground ambulances. METHODS Forces generated during transport were measured usi...

Mass-spectrometric disequilibrium analysis was applied to investigate CO2 uptake and HCO3 2 transport in cells and chloroplasts of the microalgae Dunaliella tertiolecta and Chlamydomonas reinhardtii, which were grown in air enriched with 5% (v/v) CO2 (high-Ci cells) or in ambient air (low-Ci cells). Highand low-Ci cells of both species had the capacity to transport CO2 and HCO3 , with maximum r...

Forecasts of passenger demand are an important parameter for aviation planners. Air transport demand models typically assume a perfectly reversible impact of the demand drivers. However, there are reasons to believe that the impacts of some of the demand drivers such as fuel price or income on air transport demand may not be perfectly reversible. Two types of imperfect reversibility, namely asy...

Vertical transport by moist sub-grid scale processes such as deep convection is a well-known source of uncertainty in CO2 source/sink inversion. However, a dynamical link between vertical transport, satellite based retrievals of column mole fractions of CO2, and source/sink inversion has not yet been established. By using the same offline transport model with meteorological fields from slightly...
