Examine the Role of Indo-Pacific Sea Surface Temperatures in Recent Meteorological Drought in Sudan

Atmosphere
Drought poses a serious threat to Sudan, causing water shortages, crop failures, hunger, and conflict. The relationships between Indo-Pacific teleconnections and drought events in Sudan are examined based on the Standardized Precipitation Index (SPI ...

Analisis Pola Curah Hujan Di Pulau Jawa Dengan Menggunakan Empirical Orthogonal Function (EOF)

Jurnal Pendidikan Fisika dan Sains (JPFS)
Pulau Jawa terletak di barat Indonesia adalah salah satu dari ribuan pulau yang membentuk kepulauan Indonesia. Topografi pulau ini memainkan peran penting dalam membentuk pola curah hujan. Ragam reliefnya, termasuk dataran rendah, pegunungan, lembah, dan dataran tinggi, menjadi faktor utama dalam variasi curah hujan di berbagai wilayahnya.

Feature analysis of stratospheric wind and temperature fields over the Antigua site by rocket data

Earth and Planetary Physics, 2019
The wind and temperature fields at 20 to 55 km above the Antigua launch site (17°N, 61°W) were analyzed by using sounding rocket data published by the research organization on Stratosphere-Troposphere Processes and their Role in Climate (SPARC).

Variability of upper troposphere–lower stratosphere ozone over East Asia from a perspective of atmospheric stationary waves

Environmental Research Letters
By analyzing observational reanalysis datasets since the late 20th century, in this study we investigated the monthly variability of East Asian ozone at the upper troposphere–lower stratosphere (UTLS, 250 hPa), from a perspective of atmospheric ...

基于机器学习和经验正交函数法的声速剖面快速重构

Haiyang yu huzhao
海洋声速显著影响水下声传播特性，快速获取声速剖面对水声定位、目标探测和水下通信意义重大。单变量经验正交函数法(single empirical orthogonal function regression，sEOF-r)通过建立声速剖面的经验正交系数与海表环境信息之间的线性回归关系重构声速剖面。上述方法主要存在以下不足：一是声速与海表信息并非简单的线性关系，二是逐格点重构对于大区域三维声速场重构而言计算效率低下。为此，本文基于HYCOM (hybrid coordinate ocean model ...
