Introduction: Using MOC orbital images and several image sets from MER Spirit (Pancam, Navcam and MI), it is now possible to study at substantially different scales the effects on dust drapes over soil by dust devil vortices and other surficial processes. Dust Devil Scour: MOC image R07-01606-04 covers 2.95 x 12.06 km at 1.44 m/pxl and includes the Spirit landing site atop numerous dust devil t...

To analyze the difference in microphysical development characteristics of orographic rainfall, several Parsivel disdrometers were installed along windward and leeward slope a mountain. There differences raindrop size distribution according to height distance from center In low-altitude coastal areas adjacent areas, number concentration raindrops smaller than 1 mm was relatively lower mountainou...

The WSR-57 radar a t Sacramento provides an opportunity to observe mountain effects on precipitation and on radar echo patterns. Radar patterns representing a wide range of weather situations are described and interpreted in light of concurrent gage precipitation measurements. The frequent underestimation by radar of rainfall on windward slopes is attributed to the small drop size and low forma...

Repetitively pulsed, nonequilibrium plasma discharges are studied for their ability to ignite and stabilize methane jet flames in cross flow air. The placement of the discharge is surveyed to optimize the flame duty cycle (stability). We find that flame ignition is not achieved when the discharge is located in the potential core region of the fuel jet or on the windward side of the most upstrea...

The diurnal variations in surface winds, rain, and clouds over Taiwan are presented for three rainfall regimes: the mei-yu (16 May–15 June), summer (16 July–31 August), and autumn (16 September–15 October). Though the magnitude of diurnal island divergence and convergence is similar under each regime, the diurnal variations of rain and clouds vary considerably between the regimes. These differe...
