Valley form varies throughout the study area. The region is too small to have any climatic variances, nor is the vegetation significantly different. These valley forms are primarily a function of lithologic discontinuities, structure, and multiple
Il existe une meilleure corrélation entre la lame d'eau mensuelle et le nombre de jours arrosés qu'entre cette même lame d'eau et l'intensité moyenne journalière des pluies. Mais le schéma varie en fonction de la région et de la saison. - (JPB)
Extreme daily precipitation during the period 1901-1980 Czech lands had relatively more sites with extreme totals than Slovakia. They prevailed during summer varying due to the influence of the Atlantic Ocean and the Mediterranean. (MS).

To evaluate the effects of varying debris-cover and climate on ice-melt in a maritime mid-latitude setting, an 11-day ablation stake study was undertaken on ice-cored moraine at Fox Glacier. Ablation rates varied with enhancement of melt-rate under
thin debris-covers. Air temperature from nearby Franz Josef Glacier allowed for a simple degree-day approach to ablation calculations, with regression relationships indicating air temperature is the key climatic control on melt. Digital elevation models
of the sandur appears to be strongly determined by episodic high-magnitude fluvial flows (jökulhlaups), in conjunction with surface melt. Thus, hummocky moraine appears to be a transient landform in this climatic setting.
Dans la Tunisie centrale, l'homme a toujours essayé de lutter contre la sécheresse et contre les fortes pluies. Mais sa réponse vis-à-vis de ces phénomènes varie, à la fois dans le temps et dans l'espace, en fonction du contexte géographique, aussi

. However, it is also hypothesized that, for the more complex surfaces, microadvection from adjacent land uses reduces the significance of relationships between Ts and Ta. Microadvection is expressed as a diurnally varying phenomenon, related to atmospheric
This paper will describe the late glacial and Holocene pollen and vegetation record from Poets Hill Lake and compare the results with the other sites from varying altitudes in the same region. This comparison suggests that the development of pollen
/vegetation associations was time transgressive with altitude during the late glacial when climatic influences and migration rates were important, and that the mosaic of vegetation communities became more complex during the Holocene because of adjustment
The sensitivity of soil moisture reserves to precipitation amount and frequency under current and future climates
Le nombre de jours arrosés d'un mois varie selon le logarithme naturel au carré de la hauteur d'eau reçue durant ce mois. Exemples pris au Canada. La réserve d'eau du sol est fonction de la fréquence des précipitations, plus que de leur abondance

. Storglaciären is also used as a reference for all other glaciers in the programme. In general, Swedish glaciers are still responding to the major climatic warming around 1910-1920 by retreat, and the effect of very long response times. However, measured volume
change indicates that most glaciers are close to or varying around a quasi-steady state.
One important task of site research carried out on the Tokaj-Hegyalja territory is to establish the local climatic differences developed as a consequence of the varied relief and mark out the field parts of similar characteristics. (CK).

This project was carried out as part of a national research project on the impact of climatic change on regional hydrology. The main objective was to assess the impact of climate change on overbank sedimentation rates on the embanked floodplains
in the Netherlands. The study focused on the river Rhine distributaries. One of the conclusions is that overbank sedimentations have varied in previous centuries between about 5 and 30 mm per year. Contemporary overbank sedimentation rates are highly variable
in space and time. As a result of climatic change, floodplain sedimentation rates may increase by a factor 1.5 to 2 over the forthcoming century. -(AGD)

Importance des petits réservoirs d'eau dans la formation du climat et caractéristiques des topoclimats dans les géosystèmes lacustres du Parc paysager de Suwałki
The paper attempts to answer the question, what is an influence of small lakes in an area of varied relief on a climate of adjacent areas. The study bases on topoclimatic studies within Suwałki Landscape Park. The radiation and heat balance as well
