The climate of Iowa: soil temperatures at Ames
The soil temperature observations summarized in this publication have been made possible through the cooperation of Iowa State University, the Iowa Department of Agriculture and the Weather Bureau, United States Department of Commerce. These observations constitute the only soil temperature record in Iowa of any appreciable length. Soil temperature measurements, however, have recently been initiated at Saratoga, Spencer, Council Bluffs and Burlington and are published currently by the United States Weather Bureau in the Climatological Data of Iowa (7).https://lib.dr.iastate.edu/specialreports/1021/thumbnail.jp
Our Usual Weather
This is the eighth and last in a series of articles on our weather to appear in Iowa Farm Science. This article deals with our usual weather in the state- the kinds which are typical of a location or season
Clouds - The Signposts of the Sky
To a camera enthusiast a good cloud can really make a picture. To the pilor of a plane, a cloud may be something to avoid. For those interested in the weather, to know your clouds is to know much about weather forecasting
The Air We Live In
The Earth is surrounded by a gaseous envelope which we call the atmosphere. This atmosphere extends over our heads for about 1,000 miles- becoming thinner and thinner and finally merging into interplanetary space
Why Our Weather Changes
The weather we have is caused by an interplay of a large number of different properties of the atmosphere. As the atmosphere moves, these properties change, and this makes the weather change at a particular location
How Weather Forecasts Are Made
We\u27ve been looking in previous articles in this series some of the factors that cause weather to behave as it does. Now let\u27s see how a weather forecast is made. We\u27ll look in briefly on the operations of the United States Weather Bureau - the government\u27s official weather agency
Iowa Weather Patterns
Iowa is the crossroads of many air masses, fronts and pressure areas. These combine to give the state its ever-changing weather
What is Weather?
We live at the bottom of a vast sea of air hundreds of miles deep. Without this air or atmosphere, neither animals nor plants could exist. There would be no wind, no clouds, no rain, no fire. In short, weather- and life as we know it- would not exist
How You and I Record the Weather
When you can measure what you are speaking about and express it in numbers, you know something about it, but when you cannot express it in numbers, your knowledge is of a meager, unsatisfactory kind
Sexually transmitted infection risk exposure among black and minority ethnic youth in northwest London: findings from a study translating a sexually transmitted infection risk-reduction intervention to the UK setting.
OBJECTIVES: Young black women are disproportionately affected by sexually transmitted infections (STI) in the UK, but effective interventions to address this are lacking. The Young Brent Project explored the nature and context of sexual risk-taking in young people to inform the translation of an effective clinic-based STI reduction intervention (Project SAFE) from the USA to the UK. METHODS: One-to-one in-depth interviews (n = 37) and group discussions (n = 10) were conducted among men and women aged 15-27 years from different ethnic backgrounds recruited from youth and genitourinary medicine clinic settings in Brent, London. The interviews explored the context within which STI-related risks were assessed, experienced and avoided, the skills needed to recognise risk and the barriers to behaviour change. RESULTS: Concurrent sexual partnerships, mismatched perceptions and expectations, and barriers to condom use contributed to STI risk exposure and difficulties in implementing risk-reduction strategies. Women attempted to achieve monogamy, but experienced complex and fluid sexual relationships. Low risk awareness, flawed partner risk assessments, negative perceptions of condoms and lack of control hindered condom use. Whereas men made conscious decisions, women experienced persuasion, deceit and difficulty in requesting condom use, particularly with older partners. CONCLUSIONS: Knowledge of STI and condom use skills is not enough to equip young people with the means to reduce STI risk. Interventions with young women need to place greater emphasis on: entering and maintaining healthy relationships; awareness of risks attached to different forms of concurrency and how concurrency arises; skills to redress power imbalances and building self-esteem
