Profit Sharing and Training We analyze the impact of profit sharing on the share of workers receiving training. An effect is plausible because: 1) profit sharing is a credible commitment by firms to reward firmspecific skills acquired by formal or informal training, 2) profit sharing may reduce turnover and increase the returns to training, 3) a common payment for the whole workforce leads to p...

The pioneering use of satellite-based synthetic aperture radar to characterize tropical cyclones in near-real time has provided a crucial new tool with which forecast powerful storms.

Climate Change is one of the most pressing challenges facing humanity in the 21st century. Climate simulations provide us with a unique opportunity to examine effects of anthropogenic emissions. Highresolution climate simulations produce “Big Data”: contemporary climate archives are ≈ 5PB in size and we expect future archives to measure on the order of Exa-Bytes. In this work, we present the su...

Résumé. Nous présentons une étude pour la prédiction des trajectoires de cyclones dans l’océan Atlantique Nord à partir de données issues d’images satellites. On y extrait des mesures de vitesses de vent, de vorticité, d’humidité (base JRA-25) et des mesures de latitude, de longitude et de vitesse de vent instantanée des cyclones toutes les 6 heures (base IBTrACS). Les modèles de référence à ce...

Central to tropical cyclogenesis is the changing behavior of moist convection as the cyclone evolves. Based on a cumulus ensemble model run in weak temperature gradient mode, we suggest that the mid-level vortex created by early-stage convection stabilizes the environment in way that favors further development. In particular, modeled convection occurring in the more stable environment produces ...

Daily flow records, rainfall data and tropical cyclone maps during 19701998 are used to document the impact of tropical cyclones (TCs) on floods in the Rewa River system, Viti Levu, Fiji. Floods are large, brief, isolated events caused by TCs and non-TC tropical rainstorms. More floods are caused by tropical rainstorms than by TCs, but TC floods are larger. The log Pearson Type III distribution...

Cold nutrient-rich water from below the shallow seasonal thermocline is sometimes injected into the surface layer when a storm passes in a warm season. Decrease in sea surface temperature (SST) and increase in chlorophyll-a concentration (Chl-a) in a short period due to storm passages have been clearly captured by satellite observations [1]. Understanding the short-term Chl-a increase phenomena...

A study was conducted to compare the potential of natural farming versus conventional chemical withstand adverse climate effects. The investigated two cyclones, namely cyclone Pethai and Titli 2018, which caused significant damage Andhra Pradesh’s coastal corridor. In addition, impact heavy rainfall in 2021 on different systems studied. worst-affected Paddy crop regions where these cyclones sev...
