Abstract The statistical characteristics of the winds at the Isthmus of Tehuantepec and their seasonal and interannual variability are studied through the analysis of several datasets and a reconstruction of the winds for a 31-yr period. Observations show that the long-term monthly mean wind speeds and frequency of occurrence of northerly winds have a strong seasonal signal, with maximum values during December–January, minimum during May–June, and a relative maximum in July. The frequency… 
Interannual variability of Tehuantepec eddies
[1] TOPEX/Poseidon satellite altimeter observations and the Naval Research Laboratory Layered Ocean Model simulations show interannual variability in the number and intensity of Tehuantepec eddies
Downslope windstorms in the Isthmus of Tehuantepec during Tehuantepecer events: a numerical study with WRF high-resolution simulations
Abstract. Tehuantepecers or Tehuanos are extreme winds produced in the Isthmus of Tehuantepec, blowing south through Chivela Pass, the mountain gap across the isthmus, from the Gulf of Mexico into
Spatial and temporal variability of sea breezes and synoptic influences over the surface wind field of the Yucatán Peninsula
The balance between synoptic and sea breeze atmospheric phenomena can profoundly influence atmospheric circulation in coastal regions. In this paper, a comprehensive study to understand the
Downslope windstorm study in the Isthmus of Tehuantepec using WRF high-resolution simulations
Abstract. Tehuantepecers or Tehuanos are extreme winds produced in the Isthmus of Tehuantepec, blowing south through the Chivela pass, the mountain gap across the isthmus, from the Gulf of Mexico
Low-Frequency Variability and Remote Forcing of Gap Winds over the East Pacific Warm Pool
Abstract The low-frequency variability of gap winds at the Isthmuses of Tehuantepec and Papagayo is investigated using a 17-yr wind stress dataset merging the remotely sensed observations of Special
Midsummer Gap Winds and Low-Level Circulation over the Eastern Tropical Pacific
Abstract The low-level seasonal and intraseasonal wind variability over the northeastern tropical Pacific (NETP), its relationship with other variables, and the connection with large- and
Coastal circulation in the absence of wind in the Gulf of Tehuantepec, Mexico: High-frequency radar observations
Using high-frequency radars, ocean surface currents were mapped every hour over an area of ≈5000 km2 in the inner Gulf of Tehuantepec (Mexico). The coastal circulation patterns (≈100 km offshore)
East Pacific ocean eddies and their relationship to subseasonal variability in Central American wind jets
Subseasonal variability in sea surface height (SSH) over the East Pacific warm pool off Central America is investigated using satellite observations and an eddy-resolving ocean general circulation
High-frequency response of the ocean to mountain gap winds in the northeastern tropical Pacific
[1] The wind jets generated by the three mountain gaps of Central America have a substantial impact on the mean state of the northeastern tropical Pacific. Here, we study the mean oceanic impact of


Noninertial flow in NSCAT observations of Tehuantepec winds
NASA scatterometer (NSCAT) observations provide high temporal and spatial resolution wind fields, which are used to examine gap flow through the Chivela Pass and the influence of Hurricane Marco. For
Supersquirt: Dynamics of the Gulf of Tehuantepec, Mexico
T H E LAST TWO DECADES have seen a continuing effort to observe and model the response to wind forcing in the coastal ocean along eastern boundaries of ocean basins. The emphasis of research has
Offshore wind forcing in the Gulf of Tehuantepec, Mexico: The asymmetric circulation
Since the early surveys carried out by the Eastern Tropical Pacific (EASTROPIC) and Scripps Tuna Oceanographic Research (STOR) projects in the tropical Pacific off Mexico, the northerly winds which
The midsummer drought over Mexico and Central America
Abstract The annual cycle of precipitation over the southern part of Mexico and Central America exhibits a bimodal distribution with maxima during June and September–October and a relative minimum
Inertial wind path and sea surface temperature patterns near the Gulf of Tehuantepec and Gulf of Papagayo
During the northern hemisphere winter the surface atmospheric pressure on the Gulf of Mexico side of Central America is often higher than that on the Pacific side. The resultant southward pressure
The Structure and Evolution of Gap Outflow over the Gulf of Tehuantepec, Mexico
Abstract Mesoscale-model simulations are used to examine the structure and dynamics of a gap-outflow event over the Gulf of Tehuantepec, Mexico, that was associated with a surge of cold air along the
Characteristics of wind‐generated rings in the eastern tropical Pacific Ocean
Eddies are generated in the eastern tropical Pacific (3°S–23°N, 75°–105°W) by winds blowing through Central American mountain passes from the Atlantic. We used Coastal Zone Color Scanner (CZCS) and
An Examination of the Frequency and Mean Conditions Surrounding Frontal Incursions into the Gulf of Mexico and Caribbean Sea
