Weather Monitoring

Weather monitoring at bulk handling ports enables real time management of operations to prevent pollution incidents during adverse conditions (Port Hedland Industries Council, n.d.). This may include, among others, wind speed thresholds for suspending operations, real time weather stations on site, alerts for heavy rain, storms, or high winds, operational procedures linked to weather conditions, integration with vessel scheduling, and basic manual monitoring for small ports.

For DMC ports, weather monitoring can help prevent windblown dust and cargo loss, reduce contaminated runoff during heavy rainfall, improve worker safety, avoid emergency clean up events, and protect nearby communities and ecosystems (PEMA, 2022; Wang et al., 2024).

Weather conditions significantly influence the environmental risk profile of bulk materials handling operations.

• High winds can lift dust from stockpiles, transfer points and vessel holds, dispersing particulates over wide areas and potentially exceeding air quality limits at receptor locations.
• Heavy rainfall can mobilize contaminated stormwater runoff from handling areas, overwhelming containment systems and carrying pollutants to waterways.
• Lightning and severe weather can create safety risks during operations.

Effective weather monitoring systems include, among others, fixed weather stations at representative locations across the port, wind speed and direction sensors positioned to detect conditions at ship loaders and stockpiles, rainfall gauges linked to stormwater management systems, and integration with operational control systems to trigger alerts and automated responses. Weather forecast integration supports advance planning of vessel operations, stockpile management, and contingency activities (Vaisala, n.d.).

Operational procedures commonly include wind speed thresholds for specific activities, such as suspending ship loading at certain wind speeds (varying by cargo type and exposure), restricting stockpile movement during high winds, and activating enhanced dust suppression when conditions favor emission. Thresholds are typically documented in approval conditions and/or site specific environmental management plans and communicated to operators through control room alerts and mobile notifications.

Peer reviewed research published in Environmental Pollution has developed a predictive model for dust pollution from dry bulk ports that integrates port operational data into its input features (Wang et al., 2024). Research in the Journal of Marine Science and Engineering has examined fine dust from cargo handled at a dry bulk port, noting that wind direction, temperature, humidity and atmospheric pressure influence particulate matter concentrations (Hwang and Kim, 2020).

In DMC contexts, weather monitoring is particularly important given the range of conditions encountered, including monsoon rains, tropical cyclones, dust and sand storms, and variable wind conditions.

At Port Hedland in Western Australia, where the State Government established a Dust Management Taskforce in 2009, port industry members use real time meteorological and air quality data to inform operational decisions and alter on site activities to minimize dust (Port Hedland Industries Council, n.d.).
