We focus on subseasonal predictions of the North Atlantic winter circulation by comparing hindcast experiments with different ocean model resolutions from 1991 to 2020. We find that the higher resolution of sea surface temperatures (SSTs) in the higher resolution model reveals SST warming south of the MOF and strengthening of local lower tropospheric circulation consistent with previous studies. Anomaly correlation coefficients of the atmospheric field are improved by about 0.1-0.2 in the lower-to-upper troposphere near the MOF for the higher ocean resolution. The influence of the MOF on ambient atmospheric fields is independent of El Niño Southern Oscillation conditions in both reanalysis and model. The greater accuracy of some predictions during La Niña years is probably due to the smaller errors of our model during La Niña compared with El Niño.","PeriodicalId":49501,"journal":{"name":"Sola","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135159296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Second, the map of the basin showed that the average difference in snowmelt was 22 days between upstream and downstream. On the other hand, the timing when melt forms become dominant in the snow layer was little affected by altitude and precipitation, and the dam inflow attained the peak 35 to 40 days after then.","PeriodicalId":49501,"journal":{"name":"Sola","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136047600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We modeled the power spectra of the tidal level data obtained from 12 tide stations of the Geospatial Information Authority of Japan, based on a single transfer function which converts the barometric pressure pulse spectra into the meteotsunami spectra. The pressure pulse spectra are obtained from the ensemble average of ~1500 Soratena weather sensors of Weathernews Inc. distributed over Japan. The observed meteotsunami spectra can be characterized by the enhanced seiche eigenmodes at each station excited by the mesoscale pressure pulse, which contributes for accumulating the necessary knowledge to understand the potential dangers in various different areas over Japan.","PeriodicalId":49501,"journal":{"name":"Sola","volume":"12 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83421504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kohyama","doi":"10.31223/x5ks78","DOIUrl":"https://doi.org/10.31223/x5ks78","url":null,"abstract":"On January 15, 2022, the volcano Hunga Tonga about 8000-km away from Japan explosively erupted. Following the eruption, tsunami-like sea-level fluctuations were observed in Japan, much earlier than expected based on the oceanic long-wave propagation from Tonga to Japan. By contrast, atmospheric pressure disturbance presumably due to the eruption was also observed about 30 minutes before the sea-level change. Therefore,the observed sea-level fluctuations can be considered as meteotsunamis forced by the pressure perturbation rather than tectonically forced by the eruption, but the mechanism is not yet fully understood.This study attempts to understand the nature of this meteotsunami by using a simple one-dimensional shallow-water model. The results show that the time and amplitude of the observed sea-level changes are consistent with the simulated sea-level changes forced by the atmospheric forcing. A set of experiments with different bathymetry profiles also reveals the importance of amplification due to Proudman resonance over deep basins and the shoaling effect over the continental slope, while extremely deep and narrow topography such as trenches is of second-order importance.","PeriodicalId":49501,"journal":{"name":"Sola","volume":"109 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75869918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
