Abstract While several mechanisms have been suggested to account for the association of the Arctic and Antarctic Oscillations (AO/AAO) with atmospheric parameters, this paper focuses on the relationship with the atmospheric outgoing longwave radiation (OLR). The main objective of this paper is to demonstrate through AO/AAO composite analysis that the NCEP–NCAR reanalysis OLR agrees with the independent observations of the NASA Earth Radiation Budget Experiment (ERBE) broadband satellite instruments both in zonal averages and in geographically mapped space, and to verify AO/AAO characterized general circulations derived from models and analyses. The results indicate several pronounced areas of storminess that are AO/AAO dependent. One is the well-known variation over the North Atlantic Ocean toward Europe. Also, several major areas are indicated in the tropical region—one in the Indian Ocean and the others in the west and central Pacific Ocean. In addition to demonstrating that the signals are statistically significant, also tested is the relationship of the features to other well-known tropical forcing mechanisms: the Madden–Julian oscillation (MJO) and the El Niño–La Niña sea surface temperature variations. It is shown that the tropical features do, in fact, have a strong relationship to the MJO, which indicates an additional tropical–extratropical interaction. With regard to the sea surface temperature, no correlation associated with the AO/AAO variability is seen. These associations with the cloudiness and atmospheric radiation budget suggest that if there is to be improvement of numerical model forecasts to an extended time period that numerical model radiation physics will have to be taken into consideration and improved.

The presence of skipjack fish resources in a fishing area is related to the suitability of the environmental conditions of the waters. This study aims to examine the relationship of sea surface temperature (SPL) to skipjack catches and the characteristics of skipjack catches in Manokwari waters. Data, both catch data and sea surface temperature data, are collected through field surveys by following fishing operations. Furthermore, the data were analyzed descriptively using graphs and mathematically like von Bertalanffy's growth model. The results of this study found that the very small variability of SPL could not explain the variation in the volume of fishermen's catches in Manokwari waters. However, a high SST during the May - August 2013 period is thought to affect the size of the skipjack caught, where the average size of the fish caught inhabited areas near sea level. In addition, the growth of skipjack fish in Manokwari waters is relatively fast with a growth coefficient of 0.42 per year1 and natural mortality between 0.79 per year and 0.81 per year.

Sunda Strait is an important passage for the Java Sea water to flow into the Indian Ocean. There is Java sea in North close to Karimata Strait and Eastern Indian Ocean in South part. Headed from north to south of Sunda Strait, has a high primary productivity that signifies the fertility of water. The strong El Nino (SOI) in 2015, hypothesized to affect variability values of a-chlorophyll content and sea surface temperature in this area. The research aims to know the distribution pattern of chlorophyll-a, and sea surface temperature due to El Nino effect on transition season I (March, April and May 2015). The relationship of both with SOI was analyzed by simple linear correlation analysis. The results showed that the distribution of chlorophyll-a in Northen Sunda Strait is not affected by El Nino but comes from the mouth of the Musi River. The pattern of sea surface temperature distribution from Northern to Southern of Sunda Strait showed in this area affected by El Nino so that the temperature is cooler. The relationship of chlorophyll-a with SOI has a negative moderate correlation (-0.532), indicating that chlorophyll-a in this waters have the direction opposite to SOI and sea surface temperature with SOI has a strong positive correlation (of 0.959).

Abstract The low-frequency relationship between interannual tropical and North Pacific sea surface temperature anomalies (SSTAs) in observations and a coupled general circulation model (CGCM) is investigated. The authors use the interactive ensemble CGCM, which advances a new approach for artificially increasing the signal-to-noise ratio, making it easier to detect physical and dynamical links with much reduced interference by atmospheric noise. The results presented here suggest that decadal variations in the relationship between the dominant modes of tropical and North Pacific interannual SSTA variability result from changes of spatial manifestation of North Pacific SSTA, both in the observation and in the model. The authors conjecture that the details of tropical Pacific SST forcing ultimately determine the tropical–North Pacific SST teleconnections, and this conjecture is examined in a much longer time series from a CGCM simulation. There are two patterns of North Pacific interannual SSTA variability in the model. The first pattern is locally forced by noise in the surface air–sea fluxes associated due to internal atmospheric dynamics. The second pattern is remotely forced by tropical SSTA. As the relationship of tropical–North Pacific SST teleconnections varies in the model, the spatial manifestation of the North Pacific SSTA changes from the atmospheric noise-forced pattern to the remotely forced pattern and vice versa. In the model, the amplitude of the tropical Pacific SSTA variance varies on decadal time scales and this largely determines the dominant structure of North Pacific SSTA variability. Furthermore, the change in location of the maximum tropical SST forcing is associated with the changes in the spatial manifestation of North Pacific interannual SSTA variability.

The earth's climate is constantly changing, it's just that climate change in the past took place naturally. But until now, climate change has been very closely related to human activity, so the nature of the event has become faster and more drastic. Relative humidity is a parameter that can affect climate change in Indonesia, especially in Aceh Province. Aceh province is one of the provinces located on the island of Sumatra and directly facing the Indian Ocean. Thus, Aceh Province has a considerable impact on climate change. Changes in relative humidity will lead to changes in climate elements. There are several climate elements including air temperature, rainfall, sea surface temperature, wind speed, solar radiation, and dynamic altitude. One of the methods used to look at the relationship of each climate element is the Correlation method. The purpose of this study is to find out the relationship of each variable of the climate elements. The results showed that the relationship between variables X1 (air temperature) and X3 (sea surface temperature) had the highest closeness relationship with a positive correlation value of 0.77. The lowest closeness relationships are variables X2 (rainfall) and X4 (wind speed) with a negative weak correlation value of -0.01.
