Global Frequency and Geographical Distribution of Nighttime Streamer Corona Discharges (BLUEs) in Thunderclouds
نویسندگان
چکیده
Blue LUminous Events (BLUEs) are transient corona discharges occurring in thunderclouds and characterized by strong 337.0 nm light flashes with absent (or weak) 777.4 component. We present the first nighttime climatology of BLUEs as detected Modular Multispectral Imaging Array Atmosphere-Space Interaction Monitor showing their worldwide geographical seasonal distribution. A total (land ocean) 11 occur around globe every second at local midnight average BLUE land/sea ratio is 7:4. The northwest region Colombia shows an annual peak. Globally, maximized during boreal summer-autumn, contrary to lightning which maximed summer. distribution three main regions in, order importance, Americas, Europe/Africa Asia/Australia.

On the NOx Generation in Corona, Streamer and Low Pressure Electrical Discharges
A theory developed by scientists to study nitrogen oxides, NOx, production by solar proton events shows that the NOx production rate is approximately equal to the rate of production of ion pairs during the proton impact. Since the bulk of ionization in such events is produced by secondary electron impacts, the same concept is used here to study the NOx production in low pressure discharges, cor...
متن کاملBranching of Streamer Type Corona Discharge
The behaviour of positive streamers in air is studied in a rather homogeneous field created by a short plane-protrusion gap in air. Branching is observed to be quite limited, the velocity of the streamers increases with travel distance and “late” streamers are observed. The interaction of streamer heads can be interpreted as electrostatic repulsion, while “late” streamers seem to be attracted b...
متن کاملRole of Corona Space Charge in Electrification of Convective Thunderclouds
The growth rate and maximum value of electric field inside the thundercloud of finite dimensions are calculated incorporating the effect of positive space charge produced by corona at the ground surface. Our theoretical findings reveal that the transport of corona space charge increases significantly electric dipole moment already existing in thunderclouds of moderate heights and is partly resp...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولCorona discharges: fundamentals and diagnostics
Introduction Corona discharges are discussed in this paper as one example of pulsed atmospheric discharges. Other configurations used are the dielectric barrier and the packed bed reactor. Here only the volume discharge will be discussed and not the surface discharge that also plays a role in these last two cases. The paper is divided in two parts. Fundamental processes that are important in co...
