MEDEX is a fuzzy expert system for nowcasting gale-force winds in the Mediterranean. Kuciauskas et al. (1996) and Hadjimichael et al. (1996) have described, respectively, the general development and fuzzy aspects of MEDEX, which focuses on topographically-channeled winds that occur under certain synoptic conditions. As such, a key synoptic input to MEDEX is the 500 mb circulation pattern affect...

We describe briefly the Palomar-Quest (PQ) digital synoptic sky survey, including its parameters, data processing, status, and plans. Exploration of the time domain is now the central scientific and technological focus of the survey. To this end, we have developed a real-time pipeline for detection of transient sources. We describe some of the early results, and lessons learned which may be use...

This paper presents a translation of the Arkalochori Axe and the Malia Altar Stone inscriptions, which are some of the longest known Cretan Hieroglyph inscriptions together with the Phaistos Disk. The translations are checked using two consistency criteria. First, a synoptic transliteration is used that aligns symbols from several scripts that are evolutionarily related. When the phonetic value...

It is well known that the envelope of the Madden–Julian oscillation (MJO) consists of smaller-scale convective systems, including mesoscale convective systems (MCS), tropical cyclones, and synoptic-scale waves called ‘‘convectively coupled equatorial waves’’ (CCW). In fact, recent results suggest that the fundamental mechanisms of the MJO involve interactions between the synoptic-scale CCW and ...

>20 ppm during July and August, summer diurnal cycle amplitudes increased, synoptic variability correlations improved and the gradient across the mid-continent region increased. These effects combined to reduce the squared differences between the model and high-precision tower CO2 concentrations by 20%. Synoptic transport of the large-scale N–S gradient caused significant day-to-day variability...

Social tags are user-defined keywords associated with online content that reflect consumers’ perceptions of various objects, including products and brands. This research presents a new approach for harvesting rich, qualitative information on brands from user-generated social tags. The authors first compare their proposed approach with conventional techniques such as brand concept maps and text ...

The interplay between large scale dynamics and tropospheric moisture is investigated. A simple conceptual model of the sources and sinks of humidity is used to reconstruct, using a backward Lagrangian trajectory technique, the water vapor distribution in the tropical and subtropical free troposphere. Satellite data in the water vapor channel from both Meteosat-3 and Meteosat-4 satellites are th...

This paper presents a probabilistic model for daily rainfall, using sub-sampling based on meteorological circulation. We classified eight typical but contrasted synoptic situations (weather patterns) for France and surrounding areas, using a “bottom-up” approach, i.e. from the shape of the rain field to the synoptic situations described by geopotential fields. These weather patterns (WP) provid...
