The atmospheric boundary layer (ABL) is the lowest layer of the atmosphere where surface effects are felt on time scales of about an hour. While its properties are determined by the surface characteristics, season and synoptic conditions, they in turn determine convective cloud properties and are required for the representation of cloud processes in atmospheric models. Further, interaction of the ABL with the surface layer of the ocean is a key component of ocean-atmosphere coupling. ABL characteristics over ocean surrounding the sub-continent become very important for understanding the monsoon processes during the monsoon season because the roots of many monsoon systems, that give rain to India, are over there. In this thesis data used are from three major field experiments namely the Bay of Bengal Monsoon Experiment (BOBMEX, 1999), Arabian Sea Monsoon Experiment (ARMEX, in two phases, ARMEX-I during 2002 and ARMEX-II in 2003), and Continental Tropical Convergence Zone (CTCZ) experiment (Pilot in 2009) which were carried out under the Indian Climate Research Programme (ICRP). While there have been few studies on ABL characteristics for individual cruises, a comprehensive study considering all available radiosonde data from the above cruises has been missing. This study fills this gap and focuses on the vertical structure of ABL using more than 400 high resolution Vaisala GPS radiosonde data collected over Bay of Bengal and Arabian Sea. The study attempts at first to look at the ABL characteristics of individual cruises and then compare and contrast them over the Bay of Bengal and Arabian Sea. ABL height Hm, estimated by using virtual potential temperature (θv) profile, shows diurnal variation during weak phase of convection while maximum in early morning during active phase of convection. Different variables i.e. moist static energy (h), specific humidity (q), convective available potential energy (CAPE), virtual potential temperature (θv) and equivalent potential temperature (θe) also differ during weak and active convection periods. Conserved variables mixing line approach gives the height up to which ground thermals penetrate in the vertical. This height, denoted by MH that represents the actual ABL height, is 2-3 times larger than Hm when shallow convective clouds are present. In general both Hm and MH are 20-30% larger over Arabian Sea compares to that over Bay of Bengal. Comparison of surface convective available potential energy (CAPE) and equivalent potential temperature (θe) between normal and deficit monsoon years shows that convective instability was as large in deficit years. This means that dynamic and not thermodynamics, controlled the occurrence of convection.

This thesis investigates the current interrelationship between the provisions contained in the Swedish Company Act (2005:551) and activities related to Corporate Social Responsibility (CSR) pursued by companies listed at Nasdaq Stockholm. The focal point of this thesis could be argued to be of particular relevance in this day and age, as companies listed at Nasdaq Stockholm continue to perform at the top of the league in global sustainability performance measurements, and Swedish and European legislators have intensified their efforts to encourage businesses to operate in a way that does not incur unacceptable social costs to society. Thus, most companies, particularly those with a vested interest in the private consumer market, seem to recognise the importance of fostering long-term relationships with a wide sphere of stakeholders. The purpose of the thesis has been to contribute to the steadily increasing body of legal research that discusses to what extent Swedish companies, without breaching corporate law, could involve themselves in CSR investments. Since I, initially, conclude that Swedish publicly listed companies seem to increasingly invest in activities related to CSR, the thesis also discusses whether the relevant provisions of the SCA need to change to better adapt to companies’ involvement in CSR activities. In brief, I argue, that current business research on CSR coupled with the aforementioned relevant provisions of the SCA allow boards and managing directors to pursue practically any CSR investments, and that shareholders are mostly restricted to rely on relatively blunt ex post actions against a board and/or managing director that has pursued an ill-considered CSR investment, including the obvious choices of voting to replace the board or selling their shares. And since current business research has not consistently proven the positive impact of CSR policies on the financial performance of businesses there are reasons to suspect that the law practically, due to the shielding force of the business judgment rationale and the legislator’s wish to protect most transactions, cannot be effectively applied to stop CSR investments, even if these are nothing but costs for the business. On the other hand, the findings of the thesis also suggest that the occurrence of such unwise CSR investments is not necessarily a proliferating problem, since many companies listed at Nasdaq Stockholm nowadays have powerful and short-sighted institutional owners. The situation might therefore very well be the opposite and that executives struggle to manage for the long-term, as the logic of the market tell them to do otherwise. / Den här examensuppsatsen utforskar förhållandet mellan några av aktiebolagslagens regler och det engagemang som bolag noterade på Nasdaq Stockholm uppvisar i frågor rörande Corporate Social Responsibility (CSR). Ämnet kan sägas vara särskilt relevant då såväl det samtida näringslivet som lagstiftaren tycks präglas av en ökad medvetenhet kring CSR-frågor. Den ökade medvetenheten i näringslivet förefaller alltmer inverka på affärsbeslut, ett faktum som inte minst avspeglas i de svenska bolagens topplaceringar i globala index som mäter bolags arbete med hållbarhetsfrågor. Samtidigt speglas lagstiftarens ökade medvetenhet av allt fler svenska som europeiska regulatoriska initiativ på området och vars yttersta syfte är att uppmuntra och stimulera hållbara företag som inte pådyvlar samhället oacceptabla sociala kostnader. Det är således inte särskilt anmärkningsvärt att bolagen, i synnerhet de med intressen anknutna till konsumentmarknaderna, tycks erkänna vikten av att bygga och underhålla långsiktiga relationer med en vidare krets av intressenter än deras aktieägare. Det är min förhoppning att den här uppsatsen kommer att bidra till den ständigt växande del av den aktiebolagsrättsliga diskursen som diskuterar till vilken grad bolag, utan att handla i strid med ABL:s bestämmelser, kan företa åtgärder kopplade till CSR. Eftersom jag inledningsvis anför att bolagen på Nasdaq Stockholm tycks ägna sig allt mer åt CSR diskuterar också uppsatsen om några av ABL:s bestämmelser bör förändras för att bättre hantera dessa företags allt större engagemang i CSR-frågor. Sammanfattningsvis argumenterar jag för att nuvarande företagsekonomisk forskning kring CSR tillsammans med de aktuella bestämmelsernas juridiska innebörd innebär att såväl bolagsstyrelser som verkställande direktörer kan företa i princip vilken investering relaterad till CSR som helst. Aktieägare är i praktiken hänvisade till att söka åstadkomma långsiktigt lönsamma satsningar på hållbarhet genom sanktioner ex post, exempelvis genom att sälja sina aktier eller rösta bort styrelsen. Detta innebär å ena sidan i praktiken, med tanke på att nuvarande företagsekonomisk forskning kring CSR:s inverkan på bolags vinster är tvetydig, att de relevanta bestämmelserna i ABL såsom de nu är utformade utgör en trygg hamn även för många av de transaktioner relaterade till CSR som är direkt värdeförstörande. Å andra sidan argumenterar jag i uppsatsen för att problemet med överinvesteringar i CSR inte nödvändigtvis behöver vara särskilt utbrett då bolagen och deras bolagsstyrning allt mer kommit att präglas av kortsiktiga investeringsperspektiv.
