چکیده
A hurricane (also tropical cyclone, typhoon) is a warm-core, low-pressure system that develops over tropical or subtropical waters. Most hurricanes form from a trough of low-pressure, over ocean surface temperatures greater than 26°C. As air moves across the ocean surface, it extracts moisture (water vapour) and energy (as a result of evaporation) from the ocean. The low pressure draws air inward, causing the water vapour to rise, cooling as it rises. When the vapour condenses to form clouds, it transfers the heat energy to the surrounding air. As the warm air rises higher in the atmosphere, it lowers the pressure at the ocean surface. This causes more air to enter at the ocean surface, which creates stronger winds and continues to transfer heat from the ocean into the atmosphere. As long as the atmospheric conditions are favourable and the ocean can provide the energy, this creates a feedback mechanism to strengthen the hurricane.

Effect of sea surface temperature (SST) changes on coral ecosystems in Kish Island
Background and Theoretical Foundations: Coral reefs are one of the world's most attractive ecosystems. They have been covering large parts of the world in the tropic areas. Coral reefs in the Iranian waters of the Persian Gulf are largely limited to the Islands. Many factors, including natural and anthropogenic activities cause stress to the reef communities affecting reef development. Coral bl...
متن کاملBiodiversity and distribution patterns of coral reef ecosystems in ROPME Sea Area (Inner part: Persian Gulf -Iranian waters)
The Persian Gulf is northern part of the ROPME Sea Area (RSA), and is semi-enclosed shallow sea which located in subtropical climate. Measuring is 1000km in length, varying in width 60-340km, and average depth is about 35m and maximum depth is 105m. This research was carried out during 2005-2010 for reviewing the corals status and determination of coral reef habitats distribution in the Persian...
متن کاملHydrodynamic Modelling of Coral Reefs:Ningaloo Reef-Western Australia
As with all coral reef systems, the ecology of Ningaloo Reef is closely linked to water circulation which transport and disperse key material such as nutrients and larvae. Circulation on coral reefs may be driven by a number of forcing mechanisms including waves, tides, wind, and buoyancy effects. Surface waves interacting with reefs have long been known to dominate the currents on many coral r...
متن کاملEcological Health Assessment of the Surface Sediments of the Coral Reefs of Khark and Kharko Islands (Persian Gulf, Iran)
To assess the ecological risk of the coral reef habitats of Khark and Kharko islands in the Persian Gulf, (Bushehr province), the surface sediment samples were collected from seven stations, in September 2019. The islands have a great ecological value due to the presence of coral reefs. The amounts of potentially toxic elements, sediment texture, total organic matter, total phosphorus and total...
متن کاملSpatial variation of symbiotic Dinoflagellates on coral reefs of the northern Persian Gulf
Density, mitotic index, Chlorophyll-a content and cell size of symbiotic dinoflagellates of dominant reef-building corals were measured at two different depths in Kish Island and from one depth of Larak Island in the Persian Gulf. The higher densities of symbionts were found in shallow waters of Kish Island. However, ANOVA analyses of the mitotic index yielded mixed results. The cell sizes of s...
متن کاملChemical effects of macroalgae on larval settlement of the broadcast spawning coral Acropora millepora
Recovery of degraded reefs is dependent on the settlement of coral larvae into habitats typically dominated by benthic algae, so that benthic algae may play pivotal roles in coral settlement and reef recovery. Here we demonstrate that waterborne influences of macroalgae could affect coral settlement before larvae contact reef substrata and that such effects vary between macroalgae. We tested fo...
