El Nino Southern Oscillation (ENSO) is an important driver of interannual variations in climate and ecosystem productivity in tropical regions. However, detailed information about this important phenomenon of the Indian Ocean is scarce. Consequently, the objective of this study is to improve understanding of the impact of warm event El Nino and cool event La Nina on annual tuna landings from th...

The Central Pacific El Niño (CP El Niño) has been frequently observed in recent decades. The phenomenon is characterized by an anomalous warm sea surface temperature (SST) confined to the central Pacific and has different teleconnections from the traditional El Niño. Here, simple models are developed and shown to capture the key mechanisms of the CP El Niño. The starting model involves coupled ...

The El Niño Southern Oscillation (ENSO) has significant impact on global climate and seasonal prediction. A simple modeling framework is developed here that automatically captures the statistical diversity of ENSO. First, a stochastic parameterization of the wind bursts including both westerly and easterly winds is coupled to a simple ocean-atmosphere model that is otherwise deterministic, line...

A composite NOAA 14 satellite AVHRR (Advanced Very High Resolution Radiometer) image of the Gulf of Alaska for early March 1995 reveals a sequence of six anticyclonic oceanic eddies spanning more than 1500 km of the continental margin of North America from central British Columbia to central Alaska. Although isolated mesoscale eddies have previously been documented for this eastern boundary reg...

Abstract This study demonstrates that the generalization strong anomalous equatorial Pacific westerly (easterly) winds during El Niño (La Niña) events display adjusted warm water volume (WWV) discharges (recharges) is often incorrect. Using ocean model simulations, we categorize oceanic responses to into two categories: (i) transitioning (consistent with above generalization) and (ii) neutral (...

the natural ventilation is an easy way to exchange the indoor polluted warm air with outdoor fresh air. the wind power injects outdoor fresh air into the building. a good indoor air current and subsequently a proper exhaust depend on the openings’ conditions and their situations. a serious architectural question is under what conditions of the openings the wind-cross ventilation can be effectiv...

This study presented the spatial distribution patterns of tropical cyclones (TCs) in the South China Sea (SCS) and discussed the possible influences of average sea surface temperature (SST) and the size of warm ocean eddies on changes in the intensity of TCs passing over them. Between 1993 and 2013, the SCS has experienced 233 TCs, of which 134 have interacted with warm ocean eddies. The result...

Understanding howmoose (Alces alces (L., 1758)) are affected by temperature is critical for determiningwhy populations have recently declined at the southern extent of their North American range.Warm-season heat-stress thresholds of 14 and 20 °C are commonly used to study moose, but the variable response of free-ranging moose to temperatures above these thresholds suggests thatmoosemay bemore t...

Good prediction of the behavior of wind around buildings improves designs for natural ventilation in warm climates. However wind modeling is complex, predictions are often inaccurate due to the large uncertainties in parameter values. The goal of this work is to enhance wind prediction around buildings using measurements through implementing a multiple-model system-identification approach. The ...

Investigate Japan/East Sea circulation dynamics in a systematic and progressive fashion using a sequence of increasingly complex ocean models and model-data comparisons. Investigate the impact of upper ocean topographical coupling and isopycnal outcropping on the mean pathways of the major current systems, including those over the continental shelf region. Also, to assess the impact of differen...
