Abstract The spatiotemporal evolution of daily southern Africa precipitation characteristics, and associated atmospheric circulation, related to El Niño La Niña is examined across the region’s November–April wet season. Precipitation characteristics are in terms monthly changes average precipitation, number days, heavy days three independently constructed estimates observed during 1983–2018. Me...

Since the Paris Agreement was adopted in 2015, role of space-based observations for monitoring anthropogenic greenhouse gas (GHG) emissions has increased. To meet requirements carbon dioxide (CO 2 ) emissions, European Copernicus programme is preparing a dedicated CO Monitoring (CO2M) satellite constellation that will provide and nitrogen (NO at 4 km resolution along 250 wide swath. In this pap...

Isoprene synthase converts dimethylallyl diphosphate, derived from the methylerythritol 4-phosphate (MEP) pathway, to isoprene. Isoprene is made by some plants in substantial amounts, which affects atmospheric chemistry, while other plants make no isoprene. As part of our long-term study of isoprene synthesis, the genetics of the isoprene biosynthetic pathway of the isoprene emitter, kudzu (Pue...

advantages and disadvantages of using “stokes parameters” in exploration of inertia-gravity wave properties are discussed in this paper. the survey is carried out on an inertia-gravity wave event (igws in what follows) that occurred over iran from 7 to 9 february 2012. applying this technique for investigation of atmospheric igws was recommended by vincent and fritts (1987) and then developed b...

Legumes play an important role as food and forage crops in international agriculture especially in developing countries. Legumes have a unique biological process called nitrogen fixation (NF) by which they convert atmospheric nitrogen to ammonia. Although legume genomes have undergone polyploidization, duplication and divergence, NF-related genes, because of their essential functional role for ...

Atmospheric circulations in the tropics are not well known. Beyond of its complexity, the understanding of tropical meteorology has been prejudiced by the lack of observational data. Meteorological satellites appear as important source of information to complement in-situ observations. At FUNCEME, the Ceara State Foundation for Meteorology and Water Resources, the weather and climate monitoring...

Functional plant traits are likely to adapt under the sustained pressure imposed by environmental changes through natural selection. Employing Brassica napus as a model, a multi-generational study was performed to investigate the potential trajectories of selection at elevated [CO2] in two different temperature regimes. To reveal phenotypic divergence at the manipulated [CO2] and temperature co...

The characteristic features of the boreal summer intraseasonal oscillation (BSISO) during its reinitiation period are studied using NCEP–NCAR reanalysis. Based on these observations and with the aid of an anomalous atmospheric general circulation model (AGCM), a possible mechanism responsible for the BSISO reinitiation is elucidated. The western equatorial Indian Ocean along the eastern African...
