Abstract

Research has been carried out on the distribution of chlorophyll-a in the waters of Bone Bay during high wave events based on the parameters of sea surface temperature, wind speed and ocean currents. The aim of this research is to analyze parameters related to high waves which influence chlorophyll-a concentrations in the waters of Bone Bay. Chlorophyll-a patterns in Bone Bay waters were studied based on Aqua MODIS satellite data for chlorophyll-a data and ECMWF for wind speed, sea surface temperature and ocean current data. The average value was determined using Aqua MODIS and ECMWF satellite data for 10 years from 2011 to 2020. These parameters were analyzed to determine the correlation with chlorophyll-a. The calculation results show that sea surface temperature and wind speed decreased after high waves, while ocean currents and chlorophyll-a increased after high waves in Bone Bay waters. The correlation between chlorophyll-a and wind speed is 0.15, with sea surface temperature -0.44, and with ocean currents -0.26. Spatially, high concentrations of chlorophyll-a are found in the coastal waters of the South Sulawesi region with chlorophyll-a concentrations reaching 0.4-5 mg/m3. Temporally, high chlorophyll-a concentrations occur after high wave events with an average chlorophyll-a concentration of 0.32 mg/m3.

Abstract

The aim of this research is to analyze the characteristics and performance of the air stability index threshold values ??for Cumulonimbus (CB) and Thunderstorm (TS) cloud events. This research compares the results with previous data at the Hasanuddin Meteorological Station. The analysis was carried out using Showalter Index (SI), K Index (KI), Total-Totals (TT), and Convective Available Potential Energy (CAPE) data from 2013 to 2022 with the Sturges method to determine class intervals and frequency of occurrence. Then, the performance of the threshold value was tested with 2023 data using the 2x2 contingency table verification method. The analysis results show that the threshold values ??for the air stability index, especially SI, KI, TT, and CAPE, have changed compared to previous guidelines or research. These changes are mainly in the lower threshold values, with new values ??? (-5), ? (13), ? (32), and ? (1), respectively. This shows that the frequency of CB and TS events is still influenced by this threshold value, especially at the lower limit during cloud formation. However, performance analysis in 2023 does not yet show clear significance. In general, the sensitivity of the index in predicting short-term weather is better during the day than at night, showing consistency with previous studies.
