DUNDEE (Down Under Doppler and Electricity Experiment) is described. was carried out in the vicinity of Darwin, Northern Territory, Australia, during wet seasons November 1988 through February 1989, 1989 1990. The general goal to investigate dynamical electrical properties tropical mesoscale convective systems isolated deep storms. situated at southern tip "maritime continent," experiences both monsoon "break" period conditions season. We discuss observational network deployed for present...
Abstract Statistics of tropical cyclone origin in the Australian region are presented for period July 1959‐June 1979. Cyclone genesis is found to occur preferred areas and have a high incidence coastline developments, often with precursor system forming over land. There an average 1.3 occurrences per year ‘regeneration’ whereby develops from pre‐existing which has lost intensity after crossing on continent. A synoptic analysis individual developments five years reveals that 84 cent...
Abstract The organizational modes of convection over the northern South China Sea (SCS) during onset summer monsoon are documented using radar and sounding data from May–June 1998 Monsoon Experiment (SCSMEX). occurred in mid-May with a rapid increase deep 10-day period, accompanied by major shift circulation east Asian region. Analysis Bureau Meteorology Research Centre (BMRC) Dongsha Island reveals wide range SCS. Proximity indicate that lower- middle-level vertical wind shears exerted...
Abstract Polarimetric radar data have been used to produce microphysical classifications. This kind of analysis is run in a real-time mode from several research radars, including the C-band polarimetric (C-Pol) Darwin, Australia. However, these classifications had very little systematic evaluation with independent data. Using surface often difficult because sampling issues, particularly for hail. The approach taken here use combination 50- and 920-MHz wind profiler estimates rain hail...
The AMEX observational dataset, with its high temporal and spatial resolution, has been used to study the formation structure of Tropical Cyclones Irma Jason. These systems developed evolved entirely within experiment's special observing network. is mostly based upon six hourly numerical analyses mass wind fields, on 11 vertical levels over a 1.25 lat/long grid. are traced from prior resolvable closed surface circulation when they were operationally classified as tropical cyclones....
The major field phase of the Australian Monsoon Experiment (AMEX Phase II) was conducted over northern Australia from 1 0 January to 5 February 1987. It based on collection high-density tropical upper air soundings and radar data at 12 special observation sites. These were complemented by satellite surface data, existing network, two simultaneous aircraft experiments. This paper describes collected in AMEX mean transient structure monsoon circulation during experiment. Mean across network am...
Videosonde data from an Australian squall line were combined with a radar echo profile to construct conceptual model of hydrometeor mass, number, and space charge evolution. Two‐step growth modes suggested: low‐level, warm rain‐frozen drop high‐level, graupel‐ice crystals. A riming electrification mechanism successfully explained the distribution. process was active in forward area convective region, frozen highly near 0°C level. Ice crystals, which electrified drops positively, increased...
Observations undertaken on 12 January 1990 at Darwin, Australia (12°S, 130°E), are used to document the structure of a monsoonal rainband in low-CAPE, low-shear tropical environment. Dual-Doppler radar analyses employed investigate and kinematics convective stratiform regions. A system with characteristics relatively short-lived squall line which warm rain processes play significant role production precipitation is evident. Planetary boundary layer cold-pool important organization motion...
An experiment combining wind profiler and polarimetric radar analyses of intense, but shallow, tropical thunderstorms has been performed. These storms are important as they very common along many coasts islands sometimes the precursors to large intense multicellular such occur over Tiwi Islands north Darwin, Australia. All sampled had a similar structure, with updrafts on periphery cells producing significant-sized hail downdrafts in storm center. The concentrations relatively small, have...
The BMRC Australian Monsoon Experiment is part of a concerted tropical research program aimed at improving our understanding the physics and dynamics weather systems. It based on collection high-density upper-air soundings radar data during two observational phases in October 1986 January/February 1987. objectives, background, rationale for this are described together with an overview design timetable observing component.
Data collected during the Maritime Continent Thunderstorm Experiment (MCTEX) (10 November–10 December 1995) have been used to analyze boundary layer development and circulations over two almost flat, tropical islands. The adjacent islands a combined length of about 170 km from east west 70 north south. Intense thunderstorms formed these every day field campaign. depth, temperature, circulation island measured full diurnal cycle using multiple radar analysis with surface radiosonde...
The diurnal variations in tropical cloudiness and tropospheric winds during the Australian Monsoon Experiment (AMEX) Phase II are documented compared to those observed elsewhere. A variation was found be a consistent feature of both disturbed undisturbed conditions. cloudiness, as inferred from satellite radar data, averaged over entire period AMEX II, at maximum morning ocean late afternoon Arnhem Land region northern Australia. high cloud, measured by 3:2 4:1 Land. Radar data indicated 1...
This paper describes the results of an experiment that combines data from a 5-cm-wavelength polarimetric radar and multiple-frequency wind profilers to examine signatures associated with microphysical structure several relatively shallow thunderstorms also quantitative rainfall measurements made radar. These storms produce considerable amounts centimeter-sized hail. The presence size this hail are deduced profiler data. melting particles distinctive signature large values differential...
Line integral techniques are used to calculate vertically integrated heat and moisture budgets over the Gulf of Carpentaria during Phase II Australian Monsoon Experiment (AMEX). The budget area is an array six radiosondes in a monsoon environment, calculations performed every 6 hours period 33 days. During convective outbreaks heating drying large scale by cumulonimbus activity has magnitude order 10°C day−1. sources dominated flux divergence terms, which account for 90% variance. observed...

Intralesional corticosteroids are associated with various, uncommon, local adverse events [1]. Atrophy and hypopigmentation most commonlyremain localized to sites of injection. However, outward radiation in a linear, streaky pattern has been reported is termed "perilesional/perilymphatic or atrophy [2]." We report case this rare event.
Observations are presented of a phenomenal upper tropospheric mesoscale temperature perturbation arising from the interaction between dissipating Tropical Cyclone Kerry (1979) and midlatitude trough in westerlies, which we describe as black hole its appearance on satellite imagery. We propose that this arose dynamically forced subsidence along confluence environments flow outflow major convective complex. The frequency occurrence subsequent adjustment atmosphere is described discussed.
