    Description / Table of Contents: Zusammenfassung Es wird eine einfache Gleichung für ein Frontenprofil vorgelegt. Die Form des Frontenprofiles wird für verschiedene Temperaturdifferenzen zwischen Kalt- und Warmluft und für verschiedene Werte des Druckgradienten normal zur Front berechnet. Die Abhängigkeit der Vertikalgeschwindigkeit der Warmluft an der Kaltfront von der Neigung des Frontprofiles wird ebenfalls gezeigt. Die berechnete Vertikalgeschwindigkeit an der Front ist in guter Übereinstimmung mit der mit Doppler Radar gemessenen Vertikalgeschwindigkeit.
    Notes: Summary A simple equation for frontal profile is presented. The shape of the frontal profile is calculated for various temperature differencies between cold and warm air and for different values of the pressure gradient in direction normal to front. The dependence of the vertical velocity of the warm air at a cold front and the slope of frontal profile were found too. The calculated vertical velocity at a front shows good agreement with the measured vertical velocity with Doppler radar.

    A forced 1-D convective cloud model (1988)

    Notes: Summary In order to improve prediction of some model output, an approach for the incorporation of dynamical entrainment and forced lifting into a 1-D cloud model is introduced. It is shown that: 1. The new parameterization of entrainment processes causes oscillations in the magnitudes of the vertical velocities, rain water content and temperature perturbations. 2. The forced lifting component nonlinearly amplifies vertical velocities, temperature perturbations and rain water production. It causes descents of the local maxima (positive and negative) of the parameters mentioned. 3. Model values of cloud top heights and radar reflectivity maxima with new parameter of entrainment are in better agreement with observations than former ones. The rain water mixing ratio maxima under influence of forced lifting component coincide well with observed regions of rainfall maxima.

    On the mean meridional circulation in the planetary boundary laye during the winter season in the Northern Hemisphere (1978)

    Description / Table of Contents: Zusammenfassung Es wird eine neue Methode zur indirekten Berechnung der meridionalen Oberflächengeschwindigkeit dargelegt. Auf Grund der bekannten Breitenabhängigkeit des Druckes wird eine Gleichung zur Berechnung der mittleren meridionalen Komponente der Geschwindigkeit im Winter mit Berücksichtigung der Bodenreibung abgeleitet. Mit Berücksichtigung der bekannten Werte des Windes in höheren Schichten wird der mittlere Massentransport in der planetaren Grundschicht der Nordhemisphäre berechnet. Die Berechnung ergibt, daß dieser Massentransport gegen Süden gerichtet ist und daß er größer ist als 2/3 des gesamten Massentransports nach Süden in der ganzen Atmosphäre. Die mittlere vertikale Geschwindigkeit wird aus der Kontinuität der Luftmasse in der planetaren Grundschicht berechnet. Die Differenz zwischen gemessenem und berechnetem meridionalen Windprofil in der Ekman-Schicht weist in niedrigeren Breiten größere Werte auf als in höheren Breiten.
    Notes: Summary A new method for indirect calculation of the surface meridional velocity is presented. On the base of the known latitude function of the pressure an expression is found for the calculation of the mean meridional component of velocity in the winter season, including surface friction. Together with known values of the meridional wind in the higher levels the mean mass transport at the Northern Hemisphere in the planetary boundary layer is calculated. The computation shows that the mean meridional mass transport in the planetary boundary layer is southward and that it is greater than 2/3 of the total southward mass transport in the entire atmosphere. The mean vertical velocity is calculated from the continuity of the mass of air in the planetary boundary layer. The difference between measured and calculated meridional wind profile in the Ekman layer shows greater values in the lower latitudes than at higher ones.

    The behavior of a hailstone in a forced 1-D Cb cloud model (1989)
    Springer

    Notes: Summary A forced time-dependent 1-D model of Cb cloud is used to investigate the behaviour of injected hailstones. The final hailstone radii and trajectories are calculated for three initial parameters: the initial hailstone radius, the initial hailstone density and the concentration of cloud droplets. The hailstone growth is treated as a unique process with dry, wet and melting regime. It is shown: 1) For a shallow Cb cloud with a small precipitation zone in the cloud base region the hail growth time is significantly longer than in the case without a forced lifting component. Further the recycling mechanism with/without falling down of the hail occurs. 2) For the high Cb cloud the hail growth time is longer and no recycling occurs in the case with a forced lifting component. 3) The final hailstone radius change is relatively small.

    Notes: Summary The microphysical model with the bulk water parameterization is applied to simulated both contact and deposition nucleation as well as the imersion freezing for unseeded cases and the cases immediately after seeding performed for the cold continental Cb clouds with small cloud droplets. The injection of agent AgI is performed in temperature region between −8°C and −12°C. The four groups of sensitivity experiments are executed. a. The Brownian coagulation of rain drops is the most important contact nucleation mechanism for seeded cases with great amount of rain drops. When cloud droplets mainly contribute to the liquid water content for seeded cases, the Brownian coagulation of cloud droplets is the primary nucleation mechanism while the inertial impact is the less effective contact nucleation mechanism; b. the mutual interdependence of contact and deposition nucleation mechanisms shows that the contact nucleation is more effective for graupel production than the deposition one for the temperature region considered in this model; c. the imersion freezing is the most important mechanism for all cases with significant amount of rain drops. It is more effective than the contact nucleation mechanism in unseeded cases with insufficient number of rain drops; d. the nucleation mechanisms are more sensitive to temperature changes than to pressure changes.
