Causes of the Winter Wildfires

Weather Pattern Dynamics

• Previous Years: Unusually wet winters led to extensive vegetation growth.
• Current Winter (2023-2024): Exceptionally dry conditions (according to NASA, since October, Southern California has recorded negligible rainfall) have turned this vegetation into fuel.

Santa Ana Winds

• The Santa Ana winds (strong, dry, and hot katabatic wind), a typical feature of California’s climate, significantly fanned the flames.
• Between October and January, a high-pressure system develops over the Great Basin deserts, causing winds to blow westward towards the coast.
• As these winds descend over the Sierra Nevada and Santa Ana mountains, they lose humidity (descending winds undergo compression temperature rises reduces humidity), heat up, and accelerate as they pass through mountain gaps. When they reach Southern California, the winds are fast, dry, and warm, fueling wildfires. Unusually strong Santa Ana winds are accelerating fire spread.

While lightning is a common cause of wildfires in the U.S., it was ruled out as a potential cause, as no lightning was reported in the affected areas.

Anabatic vs Katabatic wind Katabatic Wind Anabatic Wind The wind blows down a slope due to gravity (air moves downhill) Blows up a hill or mountain slope facing the Sun (air moves higher slopes). Occurs at night. Occurs during the day. It is caused by the cooling of highlands and subsequent denser air flowing downhill. It is more pronounced in calm air conditions. It is caused by the Sun heating the slope, leading to rising warm air. It is best formed on sunny days with clear skies. Foehn (warmed by compression) and Fall Wind (rapid descent without warming) are the types of Katabatic winds It has no specific subtypes.

Impact of Climate Change

• Research published in Nature Scientific Reports (2021) highlighted that California’s fire season has lengthened over the past two decades, with the peak shifting from August to July.
• Global Warming early snowmelt and longer dry seasons moisture-stressed vegetation more susceptible to wildfires (plants have less water).
• As climate change progresses, extreme weather events become more severe, leading to prolonged and intense wildfire seasons.

In 2024, California experienced its hottest June and July, along with the second-hottest October.

Potential Ignition Causes

• Strong winds can cause power lines to sway and come into contact with trees or other objects, potentially generating sparks and igniting dry vegetation. For example, the 2017 Thomas Fire was caused by Southern California Edison power lines.
• Accidental or intentional human activities, such as campfires, fireworks, etc, can also trigger wildfires.

Wildfires and Urban Water Systems

• Wildfires in urban settings pose unique challenges to water supply systems. The 2017 Tubbs Fire in Santa Rosa highlighted the potential for devastating impacts on urban water infrastructure.
• While water demand surges during firefighting efforts, many factors can disrupt water supply, including:
  • Strong winds hindering aerial firefighting operations.
  • Power outages impacting water pumping systems.
  • Damage to water pipes and infrastructure.
  • Contamination of water supplies due to low pressure and debris.

Post-fire Water Concerns

• Many areas in Los Angeles are under boil water notices due to concerns of contamination during low-pressure periods, allowing ash and debris to infiltrate the system.
• Post-fire recovery involves assessing and repairing damaged water pipes and pumps.
