Automatic cloud detection and classification using satellite cloud imagery have various meteorological applications such as weather forecasting and climate monitoring. Cloud pattern analysis is one of the research hotspots recently. Since satellites sense the clouds remotely from space, and different cloud types often overlap and convert into each other, there must be some fuzziness and uncerta...

On January 19, 1993, a very bright bolide (peak magnitude −23) crossed the sky of Northern Italy, ending with an explosion approximately over the town of Lugo (Emilia Romagna, Italy). The explosion (14 kton of energy) generated shock waves which were recorded by six local seismic stations. A reanalysis of the available data leads us to the hypothesis that the meteoroid was a porous carbonaceous...

An undescribed cellulosic chytrid with multiple rhizoidal axes, JEL142, has grouped in molecular hypotheses with Batrachochytrium dendrobatidis, the chytrid pathogen of amphibians, and thus is of interest for genetic and physiological comparisons. To describe this member of the Rhizophydiales, we examined its zoospore ultrastructure and developmental morphology. Based on a reanalysis of rDNA da...

New Caledonia has been studied by several archaeologists, yet there is much that can be clarified by a reanalysis of what has already been done. Green and Mitchell (1983:19) attempted a review and synthesis but pointed to "serious deficiencies" in the presentation of Gifford and Shutler's pioneering work from New Caledonia, published in 1956. Rather than being able to reanalyze the Gifford and ...

Synoptic situations producing rainfall at four rawinsonde observatories at eastern Spain are classified as stratiform or convective depending on dynamic and thermodynamic instability indices. Two daily radiosonde and daily-accumulated precipitation data from four observatories in Eastern Spain are used: Madrid-Barajas (MB), Murcia (MU), Palma de Mallorca (PA) and Zaragoza (ZA). We calculated tw...

Operational retrieval of Asian sand and dust storm from FY-2C geostationary meteorological satellite and its application to real time forecast in Asia X. Q. Hu, N. M. Lu, T. Niu, and P.

Meteorological information has obvious spatial-temporal characteristics. Although it is meaningful to employ a geographic information system (GIS) to visualize and analyze the meteorological information for better identification and forecasting of meteorological weather so as to reduce the meteorological disaster loss, modeling meteorological information based on a GIS is still difficult becaus...

Four years of ocean vector wind data are used to evaluate statistics of wind stress over the ocean. Raw swath wind stresses derived from the Quick Scatterometer (QuikSCAT) are compared with five different global gridded wind products, including products based on scatterometer observations, meteorological analysis winds from the European Centre for Medium-Range Weather Forecasts, and reanalysis ...

We propose that several short-duration events observed in past stellar occultations by Chiron were produced by ring material. Some similarities between these events and the characteristics of Chariklo’s rings could indicate common mechanisms around centaurs. From a reanalysis of the stellar occultation data in the literature, we determined two possible orientations of the pole of Chiron’s rings...

This paper completes the detailed presentation of our PV experiment on the 6S1/2 7S1/2 transition in Cs. A detailed description of the data acquisition and processing is given. The results of two independent measurements made on 0394F = 0 and 0394F =1 hfs components agree, providing an important crosscheck. After a complete reanalysis of systematics and calibration, the precision is slightly im...
