A Littoral Environment Observation (LEO) Program was established along the West Coast of the United States in 1968. This program provides for visual observations of waves and surf conditions to be made systematically on a daily basis. The data addressed in this report were collected at three LEO sites (as shown in Figure 1) at Pt. Mugu California, located 50 miles northwest of Los Angeles. In order to evaluate the reliability of wave heights and periods collected using the LEO techniques, comparisons of visual observations and measured wave gage records were made. The study revealed that individual visual observations of breaker height can deviate significantly from measured wave heights even when the gage wave heights had been corrected for shoaling effects. On the average the LEO observations gave a fair estimate of prevailing wave heights. LEO estimates of wave period tended to overpredict the period of maximum energy density. It is presumed that this occurred because observers often fail to count smaller waves when making this measurement. Statistics of the gage measurements of wave height and LEO wave heights are reasonably close.

Artists of Asian descent made substantial contributions to the artistic culture of the United States, incorporating practices that were different from the European-based traditions—like painting with water-soluble pigments rather than oil paint, choosing Asian subjects, and signing their works in the Asian fashion. Coming across the Pacific Ocean, some immigrants settled in Hawaii where Isami Doi, born of Japanese parents, became an influential artist. Doi typifies characteristics that are found in many Asian American artists in that he excelled at several media: printmaking, painting, and jewelry design. And he traveled extensively, spending time in Paris and over a decade in New York. The West Coast of the United States became a center for people coming across the Pacific, and major cities like Seattle, San Francisco, and Los Angeles developed Asian communities with active artistic cultures. Chinese immigrants were drawn to the San Francisco area because of the economic boom around the gold rush and the building of the railroads, but they also inspired prejudice, and harsh immigration laws were enacted in 1888. This halted immigration from China and bolstered it from Japan, until another law in 1924 restricted that as well. Yun Gee, of Chinese descent, in San Francisco made aggressively modern, brightly colored, and geometrically abstracted portraits before moving to Paris and then New York where his style became more expressionistic. The Asian communities in Seattle and Los Angeles included artists who worked in photography as well as painting, and some moved further east across the United States to pursue their careers in the Midwest or, more commonly, New York, the artistic center of the country. In the 1920s and 1930s, Yasuo Kuniyoshi became well known in the New York art world for his sensitively handled, sometimes humorous, sometimes erotic paintings and prints. Nevertheless, he and his peers who were born in Asia were forbidden by law from becoming citizens, something he desired, as his entire artistic career was in the United States. The sculptor Isamu Noguchi came to prominence after being nurtured by some of the Japanese American artists in Kuniyoshi’s circle, particularly Itaro Ishigaki. Noguchi is best known for the organically shaped carved stone sculptures he made after World War II, but he was also famous as a designer of modernist furniture and lamps using Japanese materials. Both he and Kuniyoshi suffered after the Japanese bombing of Pearl Harbor in 1941, while on the West Coast Japanese Americans were herded into detention camps, often losing their jobs and their homes in the process. Chiura Obata, for example, was removed from his prestigious teaching position at the University of California at Berkeley and put in a camp where he taught art. There he switched from making luminous landscapes of Yosemite to painting camp scenes of confinement and regimentation—once he was allowed to paint at all. The postwar years were a period of recovery, and new generations of Asian American artists emerged, exploring abstract styles and creating new incarnations of the multicultural art that was pioneered in the works of their Asian American predecessors.

We present an examination of unusually large runup events that were observed on January 16, 2016 on the west coast of the United States. Although these events resemble small tsunamis, no earthquake or significant atmospheric disturbances were observed during this time. Coincidental observations of long and rapidly increasing peak wave periods and moderately large wave heights both on- and off-shelf suggest that long and large swells generated by distant storms were possibly the cause of these events.

AbstractThe northeastern Pacific Ocean is a preferential location for the formation of closed low pressure systems. These slow-moving, quasi-barotropic systems influence vertical stability and sustain a moist environment, giving them the potential to produce or affect sustained precipitation episodes along the west coast of the United States. They can remain motionless or change direction and speed more than once and thus often pose difficult forecast challenges. This study creates an objective climatological description of 500-hPa closed lows to assess their impacts on precipitation in the western United States and to explore interannual variability and preferred tracks. Geopotential height at 500 hPa from the NCEP–NCAR global reanalysis dataset was used at 6-h and 2.5° × 2.5° resolution for the period 1948–2011. Closed lows displayed seasonality and preferential durations. Time series for seasonal and annual event counts were found to exhibit strong interannual variability. Composites of the tracks of landfalling closed lows revealed preferential tracks as the features move inland over the western United States. Correlations of seasonal event totals for closed lows with ENSO indices, the Pacific decadal oscillation (PDO), and the Pacific–North American (PNA) pattern suggested an above-average number of events during the warm phase of ENSO and positive PDO and PNA phases. Precipitation at 30 U.S. Cooperative Observer stations was attributed to closed-low events, suggesting 20%–60% of annual precipitation along the West Coast may be associated with closed lows.

This chapter details Ernst Kantorowicz's final years. Kantorowicz died of a ruptured aneurysm in September 1963. Before this, he worked on a succession of recondite articles, attended the annual meetings of the Medieval Academy and the Byzantine Institute at “Oakbarton Dumps,” vacationed on the West Coast and the Virgin Islands, and carried on earnestly with his dining and imbibing. His politics also became more leftward from the postwar years until the time of his death. For a decade and a half he was deeply worried about the possibility of nuclear war, and he held the United States responsible. During the 1950s, he was bitterly hostile to Dwight Eisenhower and Richard Nixon. On the day after Kennedy's inauguration, Kantorowicz wrote the he “couldn't be worse than Eisenhower, ” although he did change his mind.
