Some new mathematical methods for variational objective analysis
Grace Wahba,Donald R. Johnson +1 more
TL;DR: In this paper, a new and/or improved variational methods for simultaneously combining forecast, heterogeneous observational data, a priori climatology, and physics to obtain improved estimates of the initial state of the atmosphere for the purpose of numerical weather prediction are developed.
Journal ArticleDOI
The Coupling of Upper and Lower Tropospheric Jet Streaks and Implications for the Development of Severe Convective Storms
TL;DR: In this article, a hybrid isentropic-sigma coordinate numerical model is used to simulate the mass and momentum adjustments associated with a jet streak propagating in a zonal channel.
Journal ArticleDOI
Catalytic Hydrolysis of Vasoactive Intestinal Peptide by Human Autoantibody
TL;DR: Vasoactive intestinal peptide labeled with 125I, [Tyr10-125I]VIP, can be hydrolyzed by immunoglobulin G (IgG) purified from a human subject, as judged by trichloroacetic acid precipitation and reversed-phase high-performance liquid chromatography (HPLC).
Journal ArticleDOI
Evidence for eddy formation in the eastern Arabian Sea during the northeast monsoon
TL;DR: The Laccadive High (LH) as discussed by the authors is a mirrorlike counterpart to the Great Whirl, which develops during the southwest monsoon off the Somali coast (western Arabian Sea).
Book ChapterDOI
The Theory of Available Potential Energy and a Variational Approach to Atmospheric Energetics
TL;DR: The concept of available potential energy is founded upon the principle of conservation of mass and the idealization that flows, which conserve specific entropy, may exist as mentioned in this paper, and it is shown that a state of the atmosphere which possesses a minimum of total potential energy will likewise have a maximum of kinetic energy.
