Causes of Storm Surges
Storm surges are caused by wind and atmospheric pressure changes. When a storm develops over the ocean, the winds around the storm circulate in a clockwise direction in the Northern Hemisphere and counterclockwise in the Southern Hemisphere, pushing the sea waters in front of it towards the coastline. The atmospheric pressure change associated with the storm also contributes to the sea level rise.
- When the atmospheric pressure decreases, the sea level rises, creating a storm surge. This is because the decrease in atmospheric pressure reduces the pressure difference between the atmosphere and the ocean, allowing the sea water to rise.
- The wind-driven sea surface also contributes to the storm surge. The stronger the winds, the more energy is transferred to the sea surface, causing the sea level to rise.
Prediction of Storm Surges with Marine Weather Forecasting
Marine weather forecasting plays a crucial role in predicting storm surges. Forecasters use computer models and data from various sources, including weather stations, buoys, and satellites to predict the movement and intensity of storms.
Computer Models
Numerical Weather Prediction (NWP) models, such as the Global Forecast System (GFS) and the European Centre for Medium-Range Weather Forecasts (ECMWF) model, are used to forecast the movement and intensity of storms. These models predict the atmospheric conditions, including pressure, temperature, and humidity, which help forecasters predict the storm’s movement and intensity.
Data Assimilation
Data assimilation is an essential part of marine weather forecasting, allowing forecasters to incorporate data from various sources, including weather stations, buoys, and satellites, into the NWP models. This ensures that the forecast models are using the most up-to-date and accurate data available.
Forecaster Decision-making
Forecasters use the data and forecast models to make informed decisions about the movement and intensity of the storm. They also use their experience and knowledge of past storms to predict the potential impact of the storm surge on the coastline.
In summary, understanding the causes of storm surges and predicting their occurrence with marine weather forecasting are crucial for mitigating the impact of coastal erosion in Charleston, SC. By combining historical data, computer models, and data assimilation, forecasters can provide accurate predictions of storm surges, allowing residents and authorities to prepare and take necessary precautions.
