Historical climatology is an interdisciplinary field of research encompassing the reconstruction past climate and weather from written sources artifacts, as well application reconstructions to study human history. has grown in recent years, this growth brought both insights challenges. Research expanded into new regions periods diversified novel sources, methods, collaborations. At same time, h...

A 40-year climatology (1979–2018) is presented for long-track tornadoes in the United States using Storm Prediction Center tornado database. Path length (PL) stratification thresholds are defined characteristics of supercell storm evolution, and categorized as: all (ALL), PL >0 mi or 0 km; short (S), <30 48.3 long (L), [30, 60) [48.3, 96.6) very (V), [60, 90) [96.6, 144.8) extremely (X), ...

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 warning areas (CWAs), along with a discussion of selected histograms of interest. The results of the climatology indicate that a mean SLR value of 13 appears more appropriate for ...

In this chapter, we strive for something different. Whereas a goal of the other sessions at the Sierra Nevada Science Symposium was to present new research on familiar themes, our goal in the session “Climate and Landscape Change Over Time” was to introduce a topic that itself is likely unfamiliar to many resource scientists and managers. The limited discourse to date between the fields of clim...

Present-day surface wind stress climatology is manipulated to simulate wind conditions during the last glacial maximum. These estimated wind fields force a onelayer, wind-driven numerical model of the southern ocean to determine if a change in the strength of the surface wind stress can shift the location of the Antarctic Polar Front, which is part of the Antarctic Circumpolar Current. A change...
