A Numerical Case Study of the Papagayo Jet Effect on East Pacific Easterly Wave Development

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract This study investigates the development of an east Pacific easterly wave (EW) event in August 2019 and the effect of the Papagayo jet on its evolution. Convective‐permitting numerical simulations were conducted. These included a control experiment and a Gap‐Filled experiment with a closed mountain gap near the Gulf of Papagayo, to test the ...

Comparison of Fuzzy Logic and PID Control in H‐Bridge Inverter: Performance Analysis and Response Optimization

open access: yesEngineering Reports, Volume 8, Issue 2, February 2026.
Under identical conditions, we benchmark PID against Fuzzy‐Logic control for a single‐phase H‐bridge inverter. FLC achieves faster rise/settling with lower THD and better disturbance rejection than tuned PID while requiring explicit rule design—offering a reproducible baseline and deployment guidance for power‐quality‐constrained inverter applications.

Sea surface temperature and the distribution and apparent abundance of skipjack (Katsuwonus pelamis) in the Eastern Pacific Ocean, 1951-1968 [PDF]

open access: yes, 1970
ENGLISH: Isograms of sea surface temperature (OC) have been produced for 1949-1968 for the areas of the eastern Pacific Ocean in which the majority of the skipjack catch is taken. These are in the immediate coastal zone, California (35° N) to Chile (20 0
