Convective injection and photochemical decay of peroxides in the tropical upper troposphere: Methyl iodide as a tracer of marine convection
The convective injection and subsequent fate of the peroxides H2O2 and CH3OOH in the upper troposphere is investigated using aircraft observations from the NASA Pacific Exploratory Mission Tropics (A) (PEM-Tropics (A)) over the South Pacific up to 12-km altitude. Fresh convective outflow is identified by high CH3I concentrations; CH3I is an excellent tracer of marine convection because of its r...
متن کاملDirect measurements of the convective recycling of the upper troposphere.
We present a statistical representation of the aggregate effects of deep convection on the chemistry and dynamics of the upper troposphere (UT) based on direct aircraft observations of the chemical composition of the UT over the eastern United States and Canada during summer. These measurements provide unique observational constraints on the chemistry occurring downwind of convection and the ra...
متن کاملEvidence of convection as a major source of condensation nuclei in the northern midlatitude upper troposphere
We examine concurrent measurements of CN (size > 8 nm), NO, and NOy in the upper troposphere over the North Atlantic during the SONEX Experiment (Oct.-Nov., 1997). High CN and NOy observations are attributed largely to the enhancement in convective outflow. Using the ratio of NO/NOy as a chemical clock, we estimate that dilution of convective high-CN plumes is rapid (on a time scale of < 2 days...

نقش مهم آزمون مهارت شنیداری در آموزش زبان نیازمند آنست که محققان مطالعاتی را در زمینه عوامل موثر بر عملکرد زبان آموزان انجام دهند. به همین منظور، تحقیق حاضر برآن بوده که تاثیر عواملی چون نوع ارائه سوال، نوت برداری و بومی یا غیر بومی بودن گوینده را بر عملکرد زبان آموزان ایرانی مقطع پیشرفته در آزمون مهارت شنیداری بررسی نماید. در همین راستا و برای بررسی هریک از عوامل ذکر شده، یک آزمون شامل 20 سوال...
Do undiluted convective plumes exist in the upper tropical troposphere?
Using a passive tracer, entrainment is studied in cloud-resolving simulations of oceanic deep convection in radiative-convective equilibrium. It is found that the convective flux of undiluted parcels decays with height exponentially, indicating a constant probability per vertical distance of mixing with environmental air. This probability per distance is sufficiently large that undiluted updraf...
