This study examines rainfall patterns, moisture transport, and their connection to European heatwaves and blocking highs. In 2022, unprecedented rainfall in Southern Pakistan contrasted with the northern-focused rainfall in 2010. An intense cycle of low-pressure systems in 2022 transported moist air from the Indian Ocean, facilitated by southeasterly and southerly winds, and triggered deep convection, while in July 2010, southerly winds were dominant. Rossby wave breaking events in late July 2010 and late August 2022 caused the southward movement of upper-level vorticity perturbations, leading to heavy rainfall. Additionally, the heavy rainfall in Southern Pakistan in late August 2022 was influenced by concurrent intense low-pressure systems.</p>\u0000<p></p>","PeriodicalId":49501,"journal":{"name":"Sola","volume":"13 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141780079","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}

Through the empirical orthogonal function (EOF) analysis applied for austral summer-mean sea level pressure (SLP), interannual variability of the MCT is categorized into that of its intensity and zonal shift. The MCT intensity is significantly correlated to ENSO but is not correlated to regional precipitation in Mozambique. In contrast, the zonal shift of the MCT is not significantly correlated to ENSO but is correlated to regional precipitation there. A westward shift of the MCT is accompanied by the positive subtropical Indian Ocean dipole (SIOD) and strengthened Mascarene High (MH) that enhance moisture convergence over the Southern Indian convergence zone, inducing increased precipitation in southern and central regions of Mozambique. An eastward shift of the MCT is not necessarily accompanied by the SIOD but accompanied by weak suppression of the MH and precipitation there. However, if the eastward shift occurs simultaneously with the negative SIOD, it accompanies El Niño and prominent weakening of the MH, which should lead to stronger precipitation decrease in southern and central regions and increase in the northeast region of Mozambique.</p>\u0000<p></p>","PeriodicalId":49501,"journal":{"name":"Sola","volume":"25 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141738904","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}

A meteorological model coupled with a 3D RT model enables us to investigate the dependency through simulations which consider feedback of the 3D RT to the atmosphere. Using the coupled model, simulations of the isolated cumulus were conducted for grid widths ranging between 25 m and 500 m. The same series of simulations were also conducted using a conventional one-dimensional (1D) radiative transfer model and were compared with the results by the 3D RT model. The comparison clarifies that the discrepancy in liquid water path between the two RT schemes becomes more prominent with smaller grid widths. The comparison also indicates that the difference in the radiative heating is negligible for grid spacing of 500 m but was substantial for finer grid spacings. These results suggest that the 3D RT model is required to accurately simulate the feedback between clouds and shortwave radiation for an isolated cumulus with grid widths of at least 250 m or smaller, when the lateral edge of the cloud is spatially resolved.</p>\u0000<p></p>","PeriodicalId":49501,"journal":{"name":"Sola","volume":"32 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141612563","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}

This study is based on two years of observational data collected using a disdrometer installed on Hegura-jima Island, a remote island in the Sea of Japan. The analysis revealed that there are two primary types of DSD regimes over the midlatitude maritime region: “larger drop size type” (D-type) and “larger number density type” (N-type). The D- and N-type regimes are characterized by larger raindrop sizes and a higher number density of raindrops at a given precipitation intensity, respectively. Stratification with reference to the satellite-derived brightness temperature indicates that N-type regime is associated with warm rain processes, whereas D-type precipitation events occur through ice-phase processes.

Subsequently, these indices were integrated to develop a local SW monsoon index (LSWMI) in the Philippines, which was compared and assessed with climatological gridded- and ground-based rainfall datasets to quantitatively describe the spatiotemporal dynamics of the SW monsoon season over the 30-year period. Results show that the proposed LSWMI can sufficiently capture the occurrences of heavy rainfall events in western Philippines. Moreover, the LSWMI is also capable in describing the evolution (onset, peak and decay) and distinct spatiotemporal characteristics of the SW monsoon, as it propagates from northern to southern Philippines.

The seasonal progression of the ASO is found to be associated with increasing negative sea level pressure anomalies at the polar cap, reaching their maximum in March. It has been determined that the main driving force for ASO is planetary waves, with a major contribution from non-stationary waves. It is suggested that the ASO could have an impact on the occurrence of Sudden Stratospheric Warmings and Vortex Intensifications until midwinter.

Comparisons between the control and SST sensitivity runs revealed that the KLM can impact the intensity of Neoguri, even being far away from the Kuroshio. KLM-induced SST warming (cooling) enhanced (weakened) the moisture influx toward Neoguri through changes in the surface evaporation in the KP–Tokai area, indicating the penetration of wetter (drier) air parcels into the TC inner core region. The relatively wet (dry) environment in the inner core modulated the latent heating around the TC center, leading to enhancing (weakening) the distant TC. In October 2019, the KLM acted in the direction of strengthening Neoguri because the warm (cool) SST anomalies near Tokai (KP) were remarkable (insignificant).
