The Relationship

Abstract The influence of the Pacific decadal oscillation (PDO) on the relationship between El Niño and the northeast Asian summer monsoon (NEASM) is examined using observational datasets for the period of 1979–2007. When El Niño occurs during the boreal winter (December–February), the amount of rainfall over northeast Asia is usually above normal during the following summer (June–August). This relationship between El Niño and the NEASM is intensified when El Niño and the PDO are in phase during the previous winter. However, when El Niño and the PDO are out of phase, the relationship is weakened. The authors argue that the PDO can constructively or destructively interfere with the summer rainfall response over northeast Asia to El Niño. They follow the hypothesis that the summer rainfall over northeast Asia could be separated into two components, that is, the tropics-related component and the extratropics-related component. Then they argue that the PDO could modulate the relationship between El Niño and the NEASM through changes in the extratropics-related rainfall, which is associated with the atmospheric circulation, such as the Eurasian pattern. The conditional composites show that when El Niño and the PDO are in phase, the Eurasian-like pattern acts to enhance the extratropics-related rainfall over northeast Asia, resulting in the strengthening of the NEASM. In contrast, the Eurasian-like pattern acts to reduce the extratropics-related rainfall when El Niño and the PDO are out of phase, resulting in the weakening of the NEASM.

Do So

In the wake of a 1952 revolution, leaders of Bolivia's National Revolutionary Movement (MNR) embarked on a program of internal colonization known as the "March to the East." In an impoverished country dependent on highland mining, the MNR sought to convert the nation’s vast "undeveloped" Amazonian frontier into farmland, hoping to achieve food security, territorial integrity, and demographic balance. To do so, they encouraged hundreds of thousands of Indigenous Bolivians to relocate from the "overcrowded" Andes to the tropical lowlands, but also welcomed surprising transnational migrant streams, including horse-and-buggy Mennonites from Mexico and displaced Okinawans from across the Pacific. Ben Nobbs-Thiessen details the multifaceted results of these migrations on the environment of the South American interior. As he reveals, one of the "migrants" with the greatest impact was the soybean, which Bolivia embraced as a profitable cash crop while eschewing earlier goals of food security, creating a new model for extractive export agriculture. Half a century of colonization would transform the small regional capital of Santa Cruz de la Sierra into Bolivia's largest city, and the diverging stories of Andean, Mennonite, and Okinawan migrants complicate our understandings of tradition, modernity, foreignness, and belonging in the heart of a rising agro-industrial empire.
