  • Thunderstorms in San Diego and Associated Easterly Wave of 20 July 1998
    WESTERN REGION TECHNICAL ATTACHMENT NO. 00-02 FEBRUARY 15, 2000 THUNDERSTORMS IN SAN DIEGO AND ASSOCIATED EASTERLY WAVE OF 20 JULY 1998 Brandt Maxwell {Note: The figures and tables will not be printed in hard copy, but can be accessed in the Web version of theTA.] Introduction An easterly wave moved west across New Mexico, Arizona and southern California from 18-20 July 1998. During the afternoon of 20 July 1998, when the easterly wave was near San Diego, CA, thunderstorms occurred in the coastal sections of San Diego County, including the city of San Diego. This is somewhat unusual, as summer thunderstorms have occurred at the coast in San Diego on average only about once every two years (Evans and Halvorson, 1998). The thunderstorms on 20 July 1998 were short-lived, not lasting more than one hour at any one location. However, the thunderstorms were strong enough to give San Diego Lindbergh Field 0.21 inches of precipitation, which was ten times the average rainfall for the entire month of July. This was the third largest daily precipitation amount ever recorded in July at the official observation location in San Diego. It was the largest daily precipitation value in July since 31 July 1991 , when 0.23 inches of precipitation occurred during an easterly wave. Not all easterly waves that move through southern California produce precipitation in San Diego. An easterly wave (which occurred on 11 July 1999) did not produce precipitation in coastal San Diego County, despite producing flooding in the San Bernardino County mountains and deserts. An examination of these waves wi ll show that there were two major differences between the 20 July 1998 and 11 July 1999 systems.

  • WEATHER and CLIMATE Fall 2014
    GEOGRAPHY 103: WEATHER AND CLIMATE Fall 2014. MWF 10 am to 10:50 am in COM 205. (Schedule #21574) Credit: NOAA Photo Library, NOAA Central Library; Credit: NOAA GOES-12 visible imagery of Hurricane OAR/ERL/National Severe Storms Laboratory (NSSL) Katrina; 8-29-2008 COURSE DESCRIPTION Why do U.S. winds and storms typically come from the west, yet hurricanes often arrive from the east across the Atlantic Ocean? Why is it that in the summer, we have relatively few thunderstorms in southern California, while they are almost an everyday occurrence during along the coast of Florida, and for that matter in Denver too? Why do we breathe harder and get bad sunburns when we head up to the mountains to hike or ski? Why does air pollution make our blue skies gray, but make sunsets far more colorful and gorgeous? Weather and Climate introduces students to basic principles of the atmosphere such as air pressure, winds and moisture that are responsible for our blue skies, gorgeous sunsets, thunderstorms, gentle trade winds, and thin mountain air. We move on to discuss severe weather, including the phenomenon of lightning, and the unpredictable and potentially devastating hurricanes and tornadoes. We examine how our planet and its population are affected by these weather systems and how we might be influencing our global weather and climate.

  • Border Agency Fire Council
    BORDER AGENCY FIRE COUNCIL Year End Report 2011 & 2012 Border Agency Fire Council History The Border Agency Fire Council (BAFC) is made up of thirty-one United States and Mexican government agencies and organizations representing fire protection, law enforcement, legislators, emergency responders, natural resource managers, and elected officials that address public safety issues pertaining to wildfire along the U.S/Mexico international border. It is a fact that people from other countries have and will continue to enter the United States illegally by crossing from Mexico into the United States. In an effort to stop the flow of illegal immigration, in 1995 the United States government began “Operation Gatekeeper”, in an effort to tighten border security near the city of Tijuana, Baja California, Mexico. It instead pushed the crossers to the rugged east of the county and started a new immigration pattern. In desperation, people started entering on foot from the eastern part of Tijuana and without knowing, a trip that formerly took a few hours along the coast, turned into several days and involved a strenuous hike through rugged wilderness. People were not prepared for the summer heat that swelters or the winter where the temperature drops below freezing at the higher elevations. Many of these people simply didn’t understand the difficult conditions they would encounter and this lack of knowledge proved to be life threatening. The Border Agency Fire Council was formally created during the 1996 fire season, with the first meetings conducted in the fall of 1995 due to a dramatic increase in wildfire activity in southeastern San Diego County.

    U.S. Fish & Wildlife Service San Diego National Wildlife Refuge Comprehensive Conservation Plan May 2017 Volume 1 Comprehensive Conservation Plans provide long-term guidance for management decisions and set forth goals, objectives, and strategies needed to accomplish refuge purposes and identify the Service’s best estimate of future needs. These plans detail program planning levels that are sometimes substantially above current budget allocations and, as such, are primarily for Service strategic planning and program prioritization purposes. The plans do not constitute a commitment for staffing increases, operational and maintenance increases, or funding for future land acquisition. San Diego National Wildlife Refuge Final Comprehensive Conservation Plan Prepared by: San Diego National Wildlife Refuge Complex 1080 Gunpowder Point Drive Chula Vista, CA 91910 and U. S. Fish and Wildlife Service Pacific Southwest Region 2800 Cottage Way, Room W-1832 Sacramento, CA 95825-1846 Approved: Date: Implementation of this Comprehensive Conservation Plan and alternative management proposals have been assessed consistent with the requirements of the National Environmental Policy Act (42 USC 4321 et seq.).

  • 2 - the Majority (Roughly 94 Percent) of Public Lands Would Be Preserved, Except As Noted in Section 1.2.6
    1.2 DESCRIPTION OF SUBAREA The City of San Diego subarea encompasses 206,124 acres within the MSCP study area. The subarea is characterized by urban land uses with approximately three- quarters either built out or retained as open space/park system. The 1997 population within the subarea was approximately 1.3 million. The City of San Diego MHPA represents a “hard line” preserve, in which boundaries have been specifically determined. It is considered an urban preserve which is constrained by existing or approved development, and is comprised of linkages connecting several large areas of habitat. The City's MHPA is approximately 56,831 acres and includes approximately 47,910 acres within City jurisdiction, and additional City-owned lands (8,921 acres) in the unincorporated areas around San Vicente Reservoir, Otay Lakes and Marron Valley (Table 1). The City’s MHPA comprises 29 percent of the regional MHPA and 58 percent of all habitat and vacant lands. The conserved lands within the City’s MHPA total 53 percent of the vacant land in the City (61 percent of total habitat land in City). The City’s MHPA preserves 77 percent of the core biological resource areas and 77 percent of the habitat linkages within its subarea. Lands which are outside of the biological core or linkage areas but are currently dedicated or designated as open space and provide some long term conservation value are included in the City’s MHPA. In addition, a few small holdings of military properties within the City of San Diego have been included in the MHPA.

  • A Case Study of Soil Moisture and Infiltration After an Urban Fire
    fire Case Report A Case Study of Soil Moisture and Infiltration after an Urban Fire Quinn Alkin and Alicia M. Kinoshita * Department of Civil, Construction, and Environmental Engineering, San Diego State University, 5500 Campanile Dr., San Diego, CA 92182, USA; [email protected] * Correspondence: [email protected] Received: 5 May 2020; Accepted: 5 June 2020; Published: 7 June 2020 Abstract: There is an increased risk of future fire disturbances due to climate change and anthropogenic activity. These disturbances can impact soil moisture content and infiltration, which are important antecedent conditions for predicting rainfall–runoff processes in semi-arid regions. Yet these conditions are not well documented. This case study provides critical field measurements and information, which are needed to improve our understanding of mechanisms such as precipitation and temperature that lead to the variability of soil properties and processes in urban and burned landscapes. In June 2018, a fire burned a portion of the riparian zone in Alvarado Creek, an urban tributary of the San Diego River in California, United States. This fire provided an opportunity to observe soil moisture content and infiltration for one year after the fire. Three transects (one burned and two unburned) were monitored periodically to evaluate the complex spatial and temporal dynamics of soil moisture and infiltration patterns. Average dry season soil moisture content was less than five percent volume water content (%VWC) for all transects, and the burned transect exhibited the lowest %VWC during the wet season. Infiltration rates displayed a high degree of spatial and temporal variability. However, the location with the highest burn severity had the lowest average infiltration rate.
