Abstract: Input data from the AYE-SESAME I experiment are utilized to describe the effects of random errors in rawinsonde data on the computation of ageostrophic winds Computer-generated random errors for wind direction and speed ...

Abstract: A simple two-layer primitive equation (PE) model is used to study the effect of curvature on jet-streak kinematics, specifically vertical motion. Three types of vertical motion are studied: kinematic (PE) vertical motion, ...

Abstract: Terms of the balance equation were calculated at 300 mb to diagnose unbalanced flow in the upper troposphere both prior to and during a period of strong convection which took place during the AVE-SESAME I period. The sum ...

Abstract: On 30-31 January 1982 a modest low pressure system moved through the lower Mississippi Valley into western Tennessee. During this 24-hour period rain changed to snow over central Missouri and Illinois, increasing in intensity ...

Abstract: A diagnostic study of a continental occluding extratropical cyclone (ETC) during 1?2 November 1992 is presented using initializations from the Mesoscale Atmospheric Prediction System (MAPS), a hybrid sigma?isentropic ...

Abstract: Conditional symmetric instability (CSI) is an important property of the atmosphere when diagnosing and predicting mesoscale bands of moderate to heavy precipitation within winter cyclones. Within regions of CSI, slantwise ...

Abstract: Diagnostic techniques are presented that aid in determining whether a cold front is of the anafront (upslope flow) or katafront (downslope flow) type, as well as in measuring the intensity of the vertical motions in the ...

Abstract: A diagnostic/prognostic sounding analysis package is presented to aid operational forecasters. First, a diagnostic sounding analysis is shown which computes standard thermodynamic parameters while including a scheme to ...

Abstract: A mesoscale convective system (MCS) developed during the morning hours of 6 June 1993 and moved across northern and central Missouri, resulting in a narrow swath of excessive rainfall (>150 mm). The MCS developed well north ...

Abstract: A 30-yr climatology of the snow-to-liquid-equivalent ratio (SLR) using the National Weather Service (NWS) Cooperative Summary of the Day (COOP) data is presented. Descriptive statistics are presented for 96 NWS county ...
