Naath the summer islands based on africa series#
The time series of several atmospheric variables (e.g., zonal wind, precipitation, convection) also exhibited abrupt changes during the SCSSMW. Moreover, an anomalous convergent centre over Taiwan Island is prominent in the upper level. Naath are sedentary (although individual families domicile in solitary settlements) are agro-pastoralists balancing subsistence agriculture with cattle herding Naath keep large herds, fishing and hunting. The influence of the environment on the lifestyle of the Naath is obvious. In addition, the upper-level divergent centre is shifted southeastwards, as is the generating centre of tropical cyclones. Most of Naath homeland is located in the swamp areas of Upper Nile. There appears an anomalous vertical circulation cell (descending/ascending in the northern/southern SCS), which links the anomalous horizontal circulation through the Sverdrup balance. At the mid-level (500 hPa), the ascending centre moves equatorwards, shifting from the northern to the southern SCS. Changes in the upper-level (200 hPa) circulations include the deceleration of the tropical easterly stream (from the Indo-China Peninsula to the Arabian Sea) and northerly cross-equatorial flow (around the equatorial eastern Indian Ocean and Maritime Continent). The anomalous anticyclone centred over the northern SCS resembles a Rossby wave response to the reduced precipitation over the SCS and the Philippine Sea. At the low level (850 hPa), the weakening and retreat of the intertropical convergence zone (ITCZ) and rain belt in the SCS–WNP are pertinent, and the southwesterly winds over the north Indian Ocean and the SCS also weaken and retreat.
The SCSSMW is mainly defined as the westerly to easterly shift in the zonal winds due to the westwards intrusion of the western North Pacific (WNP) subtropical high in the northern SCS region. Zika virus outbreak on Yap Island, Federated States of Micronesia. This manuscript analyses the climatological characteristics (especially the synoptic phenomena and changes) of the South China Sea (SCS) summer monsoon withdrawal (SCSSMW) based on monsoon retreat dates from the National Climate Center of China Meteorological Administration. Nucleic acid amplification testing (NAAT) is used to detect Zika viral ribonucleic.
