As such, the moisture budget of individual thunderstorms is of interest. Observational studies (Braham 1952; Foote and Fankhauser 1973; Fankhauser 1988; Heymsfield and Miller 1988) have great uncertainty associated with them because of the difficulties of measuring, or even estimating relatively accurately, both the input of water vapor and the output rainfall of a storm. Numerical modeling (We...

conditions, their direct radiative effect is mainly determined by coverage and optical depth. The microphysical properties of contrail cirrus likely differ from those of most natural cirrus, at least during the initial stages of the contrail cirrus life cycle (Heymsfield et al. 2010). Contrails form and persist in air that is ice saturated, whereas natural cirrus usually requires high ice super...

This study aims 1--to describe and compare the anthropometric characteristics of male handball players from different levels of performance, and 2--to identify the morphological variables that allow differentiation of the level of performance for each individual playing position. A total of 212 male handball players (age, 23.6 ± 5.2 years) were included in this study, and divided into five leve...

Atmospheric parameters retrieved by remote sensing techniques often represent averages over considerable space or time intervals. Unresolved variability of corresponding primary physical values is a problem as soon as non-linear relations between the primary physical value and the retrieved parameter come into play, as for example the R(Z)relation between radar reflectivity Z and rain rate R. W...

The effects of cirrus clouds on the radiation budget of the earth and the atmosphere, and hence their impact on weather and climate processes, have been articulated by Liou (1986, 1992). Cirrus clouds are frequently finite and highly inhomogeneous based on satellite and replicator sounding observations (Ou et al. 1995; Heymsfield and Miloshevich 1993). Potential effects of the cloud geometry an...

There are undeniable changes in the body's composition with old age, and these changes can bring about a plethora of physiological consequences affecting levels of function, and current and subsequent health (Rosenberg, 1989; Heymsfield et al. 1995). Health and function are interrelated states within the ageing process (Nagi, 1976), and transitions amongst them and disease and disability are af...
