High-Frequency Mixed Rossby-Gravity Waves in the Mid-Troposphere Triggered Kerala Floods of 2018

چکیده
Kerala, the South-West coastal state of India, was ravaged by a series floods during Monsoon 2018. The season marked severely anomalous rainfall trends, with over 100 mm departures from mean daily precipitation in northern districts State. Unlike previous works, this study not only documents extreme event, but also identifies tropical dynamics responsible for it. synoptic disturbances Pacific triggered high-frequency Mixed Rossby-Gravity (MRG) waves mid-troposphere Boreal Summer, which meddled trough, as it propagated westward east Equatorial Indian Ocean to coast Africa. Interestingly, these equatorially-trapped were found have teamed up Madden–Julian Oscillations (MJO) fuel deep convection tropics and caused heavy Kerala

The influence of orographic Rossby and gravity waves on rainfall
Orography is known to influence winter precipitation in Asia and the Indo-Pacific Ocean by mechanically forcing winds, but the dynamics involved in the precipitation response are incompletely understood. This study investigates how two types of orographically forced oscillatory motions alter time-mean winds and precipitation. The quasi-geostrophic omega equation is used together with previous i...
متن کاملMixed Rossby–Gravity Waves and Western Pacific Tropical Cyclogenesis. Part I: Synoptic Evolution
A large-amplitude mixed Rossby–gravity wave packet is identified in the western Pacific using 6–10-day bandpass-filtered winds. Individual disturbances of 2300–3000-km wavelength propagated westward as the packet moved slowly eastward. The packet first appeared, and subsequently amplified, within a region of active convection associated with the Madden–Julian oscillation (MJO), which was isolat...
متن کاملinvestigation of rossby and inertia gravity waves based on proper orthogonal decomposition (pod) in beta plain
in the present work properties of rossby and inertia gravity waves are investigated based on proper orthogonal decomposition (pod) functions. the pod functions are constructed using analytical, experimental or numerical data recorded as snapshots. the pod basis can be carried out to make a reduced order model by galerkin projection of governing equations onto these functions. in this paper, the...
