Atmospheric Rivers and Business Impacting Weather

In the world of meteorology, atmospheric rivers are a fascinating and impactful phenomenon that often take center stage in discussions about extreme weather events. These narrow, concentrated channels of moisture-laden air play a crucial role in shaping the climate and weather patterns of regions around the world. That is why it is important for business decision-makers to be aware of what atmospheric rivers are and crucial for them to track any business-impacting weather that results from them. In this blog post, we will delve into the intricacies of atmospheric rivers, exploring what they are, what causes them, their effects on weather, their impact on businesses, and how climate change is influencing these weather giants.


What Are Atmospheric Rivers?

Atmospheric rivers are concentrated channels of moisture in the atmosphere that play a vital role in the Earth’s hydrological cycle. These atmospheric “rivers” can stretch thousands of kilometers across the sky, typically moving horizontally from the tropics to higher latitudes. They are characterized by their high moisture content and can transport an astonishing amount of water vapor, often exceeding the flow of water in the world’s largest rivers. While they contribute to beneficial precipitation, they can also lead to flooding, making them an important focus of weather and climate research and forecasting.


Atmospheric rivers are like “rivers in the sky” that carry vast amounts of water vapor from one region to another. These air masses are rich in water vapor due to warm ocean temperatures. They are responsible for transporting a significant portion of the world’s moisture from tropical and subtropical regions to mid-latitude and polar regions. Atmospheric rivers are relatively narrow, typically spanning a few hundred miles in width. Within this corridor, the concentration of moisture is exceptionally high, often exceeding that of the surrounding atmosphere. One of the most notable atmospheric rivers is the Pineapple Express, which brings tropical moisture from near Hawaii to the United States’ West Coast.


Weather and Climate Impacts

When an atmospheric river makes landfall or interacts with other weather systems, it can bring about significant weather events. The most common impacts include heavy rainfall, intense snowfall in mountainous regions, and the potential for flooding, both from rainfall and snowmelt. These events can lead to landslides, flash floods, and river flooding. While atmospheric rivers can cause destructive weather events, they also contribute to the water supply in many regions. They have the ability to replenish water resources, including reservoirs, groundwater, and snowpack, which can be critical for agriculture, drinking water, and hydropower generation.


Tracking and Monitoring

Meteorologists and climate scientists use various tools and technologies, including satellite imagery and computer models, to monitor and track atmospheric rivers. This monitoring helps in predicting their behavior and potential impacts on weather events and climate.


Atmospheric Rivers Impact on Business

Atmospheric rivers can have a multifaceted impact on businesses across various sectors, and their influence can be both positive and negative. These impacts are often location-specific and depend on the intensity and duration of the atmospheric river event, as well drought and watershed conditions in the impacted regions. To adapt to these challenges and capitalize on potential benefits, businesses should incorporate robust weather risk management strategies, invest in infrastructure resilience, and stay informed about changing weather patterns exacerbated by our adapting atmosphere. Collaboration between governments, businesses, and meteorological agencies is crucial to managing the impacts of atmospheric rivers effectively.



Atmospheric rivers can bring much-needed relief to drought-stricken agricultural regions by providing a significant influx of moisture. This can replenish soil moisture levels, improve crop yields, and enhance the overall health of crops. On the flip side, excessive rainfall from intense atmospheric rivers can lead to waterlogged fields, soil erosion, and damage to crops. This can delay planting and harvesting, reduce crop quality, and result in financial losses for farmers.


Infrastructure and Construction

The heavy rainfall associated with atmospheric rivers can lead to flooding and landslides, damaging roads, bridges, and other infrastructure. Construction projects may be delayed or interrupted, incurring additional costs, and creating safety hazards for workers.



Atmospheric rivers can disrupt transportation networks through flooding, road closures, and landslides. This disruption can affect the movement of goods and people, leading to supply chain interruptions and increased shipping costs for businesses reliant on timely transportation.


Energy and Utilities

Hydropower generation facilities can benefit from the increased water supply brought by atmospheric rivers, leading to higher power output during and after these events. Conversely, excessive rainfall from atmospheric rivers can cause reservoirs to overflow, potentially damaging hydropower infrastructure. In regions where power generation relies heavily on hydropower, such events can disrupt energy production.


Insurance and Risk Management

Insurance companies often face a surge in claims during and after weather events caused by atmospheric rivers, as businesses and homeowners seek coverage for flood and storm damage. This increased claims activity can strain the financial resources of insurance companies and lead to higher premiums for policyholders.


Retail and Hospitality

Severe weather events, including those caused by Atmospheric rivers, can deter customers from shopping or traveling, impacting businesses in the retail and hospitality sectors. Reduced foot traffic and cancellations can lead to revenue losses for restaurants, hotels, and retail establishments.


Coastal and Maritime Industries

Coastal businesses, such as shipping and fishing, may be adversely affected by Atmospheric rivers through rough seas, coastal erosion, and disruptions in maritime operations. Ports may experience closures or delays, impacting international trade.


Mitigate the Weather Risks Associated with Atmospheric Rivers

Atmospheric rivers are an awe-inspiring aspect of Earth’s weather systems. While they play a vital role in maintaining our planet’s hydrological balance, their resulting weather events have the potential for destruction and disruption. Understanding the causes, effects, and evolving dynamics of atmospheric rivers is essential as we navigate a world where our changing atmosphere is reshaping the way these weather giants interact with our environment. Businesses must adapt to these new norms in extreme weather and work with accurate weather insights to mitigate their impacts.
