Quasi-Biweekly Oscillation of the Convection around Sumatra and Low-Level Tropical Circulation in Boreal Spring
Publisher: American Meteorological Society
Abstract: The quasi-biweekly oscillation (QBWO) of the tropical convection around Sumatra and its relation to the low-level circulation over the tropical Indian Ocean in boreal spring is investigated. From March to May, the convection ...
How Did Air Pollution Change during the COVID-19 Outbreak in China?
Publisher: American Meteorological Society
Abstract: In early December 2019, an outbreak of the novel coronavirus pneumonia (COVID-19) occurred in Wuhan, Hubei Province, China, and spread fast throughout China. As of 15 June 2020, there have been about 84,000 confirmed cased ...
The Contribution of Boreal Spring South Pacific Atmospheric Variability to El Niño Occurrence
Publisher: American Meteorological Society
Abstract: Despite the fact that great efforts have been made to improve the prediction of El Niño events, it remains challenging because of limited understanding of El Niño and its precursors. This research focuses on the influence ...
Impact of Spring Soil Moisture on Surface Energy Balance and Summer Monsoon Circulation over East Asia and Precipitation in East China
Publisher: American Meteorological Society
Abstract: umerous studies have been conducted on the impact of soil moisture on the climate, but few studies have attempted to diagnose the linkage between soil moisture and climate variability using observational data. Here, using ...
Effect of Spring Precipitation on Summer Precipitation in Eastern China: Role of Soil Moisture
Publisher: American Meteorological Society
Abstract: AbstractThe relation of spring (March?May) to summer (July?August) precipitation in eastern China is examined using observed data. It is found that when spring precipitation from the lower and middle reaches of the Yangtze ...
Comparing Occurrences and Vertical Structures of Hydrometeors between Eastern China and the Indian Monsoon Region Using CloudSat/CALIPSO Data
Publisher: American Meteorological Society
Abstract: Seasonal variations in the occurrence frequency, vertical location, and radar reflectivity factor (dBZ) of hydrometeors covering eastern China and the Indian monsoon region are described using two CloudSat standard products ...
Distinct Modes of the East Asian Winter Monsoon
Publisher: American Meteorological Society
Abstract: Two distinct modes of the East Asian winter monsoon (EAWM) have been identified, and they correspond to real and imaginary parts of the leading mode of the EAWM, respectively. Analyses of these modes used the National ...
Impact of East Asian Winter and Australian Summer Monsoons on the Enhanced Surface Westerlies over the Western Tropical Pacific Ocean Preceding the El Niño Onset
Publisher: American Meteorological Society
Abstract: omposite analysis from NCEP?NCAR reanalysis datasets over the period 1948?2007 indicates that stronger East Asian winter monsoons (EAWM) and stronger Australian summer monsoons (ASM) generally coexist in boreal winters ...
The Initiation and Developing Mechanisms of Central Pacific El Niños
Publisher: American Meteorological Society
Abstract: he initiation and developing mechanisms of four major central Pacific (CP) El Niño events in 1994, 2002, 2004, and 2009 were investigated by analyzing oceanic and atmospheric reanalysis data. A mixed layer heat budget ...
The Relationship between Soil Moisture and LAI in Different Types of Soil in Central Eastern China
Publisher: American Meteorological Society
Abstract: s important parameters in the land?atmosphere system, both soil moisture (SM) and vegetation play a significant role in land?atmosphere interactions. Using observational data from clay and sand stations over central eastern ...
