    Notes: Abstract —The Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS) is used to investigate the mutual response of a tropical squall line and the ocean. Simulated squall line compares well with the observations, and consists of counterrotating vortices, and has a bow shape bulge toward the leading edge. In addition to these features, which are also shown in the previous numerical simulations, the unique results from the coupled simulation indicate that the air–sea interaction processes within the squall line are important. They affect both the atmosphere and the ocean locally. Simulated upper ocean displays significant response to the squall line with upwelling and baroclinicity. Depth of the ocean mixed layer in the coupled simulation becomes modified due to feedback processes. Ocean temperature acts as a destabilizing factor, and the salinity as a stabilizing factor. Surface turbulent fluxes from the coupled simulation are about 10% less than that of the uncoupled simulation. The SST in the coupled simulation decreases by about 0.21°C. Predicted squall line in the coupled simulation is weaker as compared to the uncoupled simulation. This is reflected in terms of differences in surface fluxes, cloud water, rain water and vertical velocities between the two simulations.

    Description / Table of Contents: Zusammenfassung Die Chemie der Verdampfung von In2Te3(s) wurde mittels automatisierter gleichzeitiger Anwendung derKnudsen- und Torsions-Effusion, mittels Hochtem-peraturmassenspektrometrie und entsprechenden Hilfsmethoden untersucht. Es wird über die ersten absoluten Messungen des Dampfdrucks von In2Te3 berichtet. In2Te3(s) verdampfte inkongruent im Temperaturbereich von 701–889 K, wobei Te2(g) und eine feste Lösung mit der ZusammensetzungX In=0.42 undX Te=0.58 entstand. Die Standard-Enthalphie der Reaktion bei 298 K, ΔH° (298 K), war nach der Methode des dritten Gesetzes 136.0±0.3 kJ/mol. Die erwähnte feste Lösung verdampfte inkongruent unter Bildung von InTe(s) und einem Dampf, der aus Te2(g) und In2Te(g) bestand. InTe(s) verdampfte im Bereich von 701–887 K kongruent unter Bildung von Te2(g) und In2Te(g); ΔH v ° (298 K) nach dem dritten Gesetz war 201.5±1.0 kJ/mol. Diese Ergebnisse sind im Gegensatz zu Literaturangaben zur Verdampfung von In2Te3, wobei sowohl kongruente als auch inkongruente Verdampfung zu InTe(s) berichtet wurden. Außerdem wurde InTe(s) als inkongruent verdampfend beschrieben. Diese Abweichungen werden diskutiert.
    Notes: Abstract The vaporization chemistry of In2Te3(s) was studied by the computer-automated simultaneousKnudsen-effusion and torsion-effusion method, by high-temperature mass spectrometry, and by ancillary methods. The first absolute measurements of the vapor pressure of In2Te3 are reported. In2Te3(s) vaporized incongruently in the temperature range 701–889 K and produced Te2(g) and a solid-solution, (X In=0.42 andX Te=0.58). The standard enthalpy of the reaction at 298 K, ΔH° (298 K) by the third-law method was 136.0±0.3 kJ/mol of vapor. The above solid solution vaporized incongruently and produced InTe(s) and a vapor which consisted of Te2(g) and In2Te(g). InTe(s) vaporized congruently in the range 701–887 K and produced Te2(g) and In2Te(g); the third-law ΔH v ° (298 K) was 201.5±1.0 kJ/mol. These results were at variance with the literature on vaporization of In2Te3 where both congruent vaporization and incongruent vaporization to give InTe(s) are separately reported. Further, InTe(s) was reported to vaporize incongruently. These differences are discussed.
