35. On calculating the buoyancy of cores in a convective boundary layer

Abstract

Aircraft measurements of vertical air motions are used in a process of conditional sampling to select updraft and downdraft cores during a period of strong lake-effect convection. Corresponding measurements of temperature and moisture are used to calculate the buoyancies of the cores and to evaluate the dependence of the calculated buoyancy on the horizontal extent of core environment used in the calculations. Results suggest that calculated buoyancies are relatively insensitive to the definition of core environment.

38. Lake-effect snowfall over Lake Michigan

Author

Abstract

The amount and distribution of snowfall vary over the waters Lake Michigan. The variance is influenced by midlatitude cyclonic storms and lake-effect meoscale weather systems. Temperature, precipitation and frequency of midlake band storms effect the rate of increase of snow cover over Lake Michigan. The Cloud Physics Group of University of Chicago conducted a quantitative study during December 1980, January 1981, December 1983 and January 1984. Snow over the southern basin of the lake is more than that in the snowbelt along Michigan shore. This increase in snowfall amount is prominent when midlake-type storms occur.

Abstract

The public human genome sequencing project utilized a hierarchical approach. A large number of BAC/PAC clones, with an insert size approximate from 50 kb to 300 kb, were identified and finely mapped with respect to the Sequence Tagged Site (STS) physical map and with respect to each other. A "golden path" of BACs, covering the entire human genome, was then selected and each clone was fully sequenced. The large number of remaining BACs was not fully sequenced, but the availability of the end sequence (~800-1000 bp) at each end allowed them to be very precisely mapped on the human genome.The search for copy number variations of the human genome used several strategies. One of these approaches took advantage of the fact that fosmid clones, contrary to BAC/PAC clones, have a fixed insert size (~40 kb) (Kidd et al., Nature 453: 56-64, 2008). In this context, the ends of ~7 million fosmid clones were sequenced, and therefore it was possible to precisely map these clones on the human genome.In summary, a large number of genomic clones (GC) are available for FISH experiments. They usually yield bright FISH signals and are extremely precious for molecular cytogenetics, and in particular cancer cytogenetics. The already-labeled probes available commercially are usually based on a combination of such GCs. The present chapter summarizes the protocols for extracting, labeling, and hybridization onto slides of DNA obtained from GC.
