Highly short-term forecasting, or nowcasting, of heavy rainfall due to rapidly evolving mesoscale convective systems (MCSs) is particularly challenging for traditional numerical weather prediction models. To overcome such a challenge, a growing number of studies have shown significant advantages of using machine learning (ML) modeling techniques with remote sensing data, especially weather radar data, for high-resolution rainfall nowcasting. To improve ML model performance, it is essential first and foremost to quantify the importance of radar variables and identify pertinent predictors of rainfall that can also be associated with domain knowledge. In this study, a set of MCS types consisting of …

As part of HJ47/SJ47 (2020), the Virginia General Assembly directed the Joint Commission on Technology and Science (JCOTS) to study the “safety, quality of life, and economic consequences of weather and climate-related events on coastal areas in Virginia.” In pursuit of this goal, the commission was to “accept any scientific and technical assistance provided by the nonpartisan, volunteer Virginia Academy of Science, Engineering, and Medicine (VASEM). VASEM convened an expert study board with representation from the Office of the Governor, planning district commissions in coastal Virginia, The Port of Virginia, the Virginia Economic Development Partnership, state universities, private industry, and …

North Polar Frontal Clouds And Dust Storms On Mars During Spring And Summer, Huiqun Wang, Jenny A. Fisher
North Polar Frontal Clouds And Dust Storms On Mars During Spring And Summer, Huiqun Wang, Jenny A. Fisher
Jenny A Fisher
The complete archive of Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) Mars Daily Global Maps (MDGM) are used to study north polar clouds and dust storms that exhibit frontal structures during the spring and summer (Ls 0–180°). Results show that frontal events generally follow the edge of the polar cap during spring and mid/late summer with a gap in the distribution in early summer. The exact duration and timing of the gap vary from year to year. Twww.lw20.comen to twenty percent of spring and summer time frontal events exhibit complex morphologies. Distinct temperature signatures are associated with features observed …

Localized Storms, Edward A. Bryant

The previous chapter was mainly concerned with the effects of strong winds generated by secondary features of general air circulation. These winds were associated with the development of low-pressure cells spanning areas of 10,000–100,000 km−2. While tropical cyclones and extra-tropical depressions produce some of the strongest winds and highest amounts of precipitation over the widest areas, they are by no means the only source of high winds or heavy precipitation. These values can be matched by thunderstorms, which cover no more than 500 km2 in area and rarely travel more than 100–200 km before dissipating. They can produce high-magnitude, short-period …

Coastal storms have been considered significant agents in transporting sediment, modifying morphology and causing recent beach erosion. Along the New South Wales coast, the concomitance of storms, warmer sea surface temperatures and poleward movement of the Hadley cell was linked to beach erosion on Stanwell Park beach between 1943 and 1978. This result was defined using an accurately constructed compilation of coastal storms and a precisely measured time series of high tide positions taken from 105 oblique photographs. The two data sets are amongst the best of their kind in the world. Indices of storm magnitude, representing cumulative significant wave …

Between May 24th and June 18th 1974, three periods of erosive wave conditions dramatically changed the character of many beaches along the central and southern New South Wales Coast. This paper documents and evaluates regional variations in the responses of beaches to these erosional events for selected portions of this coast (Figure 1).
